Question 1. A Man, His Wife And Daughter Worked In A Graden. The Man Worked For three Days, His Wife For 2 Days And Daughter For four Days. The Ratio Of Daily Wages For Man To Women Is 5 : 4 And The Ratio For Man To Daughter Is five : 3. If Their Total Earnings Is Mounted To Rs. One hundred and five, Then Find The Daily Wage Of The Daughter?

Answer :

Assume that the daily wages of guy, girls and daughter are Rs 5x, Rs. 4x, Rs 3x respectively.

Multiply (no. Of days) with (assumed daily wage) of all and sundry to calculate the cost of x.

[3 x (5x)] + [2 x (4x)] + [4 x (3x)] = 105

[15x + 8x + 12x] = one zero five

35x = a hundred and five

x = 3

Hence, guy's every day salary = 5x = five x three = Rs. 15

Wife's day by day salary = 4x = four x three = Rs. 12

Daughter's day by day wage = 3x = 3 x three = Rs. Nine.

Question 2. Amit, Raju And Ram Agree To Pay Their Total Electricity Bill In The Proportion three : four : five. Amit Pays First Day's Bill Of Rs. 50, Raju Pays Second Day's Bill Of Rs. Fifty five And Ram Pays Third Day's Bill Of Rs. Seventy five. How Much Amount Should Amit Pay To Settle The Accounts?

Answer :

Toatal bill paid by Amit, Raju and Ram = ( 50 + fifty five +75 ) = Rs. 180

Let quantity paid by using Amit, Raju and Ram be Rs. 3x, 4x and 5x respectively.

Therefore, (3x + 4x + 5x ) = one hundred eighty

12x = 180

x = 15

Therefore, quantity paid via,

Amit = Rs. 45

Raju = Rs. 60

Ram = Rs. Seventy five

But definitely as given inside the query, Amit can pay Rs. 50, Raju can pay Rs. 55 and Ram pays Rs. 80. Hence, Amit will pay Rs. 5 less than the real quantity to be paid. Hence he wishes to pay Rs. 5 to Raju settle the amount.

Question three. Salaries Of Ram And Sham Are In The Ratio Of four : 5. If The Salary Of Each Is Increased By Rs. 5000, Then The New Ratio Becomes 50 : 60. What Is Sham's Present Salary?

Answer :

Assume authentic salaries of Ram and Sham as 4x and 5x respectively.

Therefore,

(4x + 5000)/= 50

(5x + 5000) 60

60 (4x + 5000) = 50 (5x + 5000)

10 x = 50,000

5x = 25, 000

Sham's gift earnings = 5x + 5000 = 25,000 + 5000

Sham's present earnings = Rs. 30,000.

Question 4. Two Dice Are Tossed.The Probability That The Total Score Is A Prime Number Is?

Answer :

Clearly, n(S) = (6 x 6) = 36.

Let E = Event that the sum is a high wide variety.

Then E= (1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, five), (three, 2), (three, four), (4, 1), (4,three),(5, 2), (5, 6), (6, 1), (6, five)

n(E) = 15.

P(E) = n(E)/n(S) = 15/36 = five/12.

Question 5. Find The Lcm Of Following Three Fractions:36/,48/,72/?

Answer :

Numerators = 36, 48 and 72.

72 is largest number amongst them. 72 isn't divisible with the aid of 36 or forty eight

Start with desk of 72.

Seventy two x 2 = 144 = divisible by means of 72, 36 and forty eight

? LCM of numerators = a hundred and forty four

Denominators = 225, a hundred and fifty and 65

We can see that they may be divided by using five.

On dividing by means of five we get forty five, 30 and 13

We can't divide similarly.

So, HCF = GCD = five

LCM of fraction =one hundred forty four/five.

Question 6. Find The Largest Number To Divide All The Three Numbers Leaving The Remainders four, three, And 15 Respectively At The End?

Answer :

Here finest range that can divide manner the HCF

Remainders are exclusive so certainly subtract remainders from numbers

17 - four = thirteen; forty two - 3 = 39; 93 - 15 = 78

Now allow's discover HCF of 13, 39 and 78

By direct remark we can see that every one numbers are divisible by means of thirteen.

? HCF = 13 = required finest wide variety.

Question 7. The Two Given Numbers A And B Are In The Ratio 5:6 Such That Their Lcm Is 480. Find Their Hcf?

Answer :

Let K be not unusual component. So 2 numbers are 5K and 6K

Also K is the finest commonplace thing (HCF) as five and 6 haven't any other common component

? 5K x 6K = 480 x K

K = 16 = HCF.

Question 8. A Wall Is 4.5 Meters Long And 3.5 Meters High. Find The Number Of Maximum Sized Wallpaper Squares, If The Wall Has To Be Covered With Only The Square Wall Paper Pieces Of Same Size?

Answer :

Wall can be blanketed most effective by means of using rectangular sized wallpaper portions.

Different sized squares are not allowed.

Length = four.5 m = 450 cm;

Height = 3.Five m = 350 cm

Maximum rectangular length viable way HCF of 350 and 450

We can see that 350 and 450 can be divided with the aid of 50.

On dividing by using 50, we get 7 and 9.

Since we can't divide similarly,

HCF = 50 = size of side of rectangular

Number of squares =Wall place/=450 x 350/= sixty three

Square place=50 x 50.

Question 9. Find The Largest Number Of four-digits Divisible By 12, 15 And 18?

Answer :

Required largest range have to be divisible by means of the L.C.M. Of 12, 15 and 18

L.C.M. Of 12, 15 and 18

12 = 2 × 2 × three

15 =5 × three

18 = 2 × 3 × three

L.C.M. = one hundred eighty

Now divide 9999 by using one hundred eighty, we get remainder as ninety nine

The required biggest wide variety = (9999 – ninety nine) =9900

Number 9900 is exactly divisible with the aid of 180.
