25 * 2 * zero.Seventy five = 20/100 * 10/a hundred * 7.5/100 * x

25 =  1/100 * x => x = 25000.

Question 60. If The Length, Breadth And The Height Of A Cuboid Are In The Ratio 6: 5: four And If The Total Surface Area Is 33300 Cm2, Then Length Breadth And Height In Cms, Are Respectively?

Length = 6x

Height = 4x in cm

Therefore, 2(6x × 5x + 5x × 4x + 6x × 4x) = 33300

148x2 = 33300

=> x2 = 33300/148 = 225

=> x = 15.

Therefore, Length = 90cm,

Height = 60cm

ninety, seventy five , 60 cm.

Question sixty one. The Sum Of Three Consecutive Integers Is 102. Find The Lowest Of The Three?

Three consecutive numbers may be taken as (P - 1), P, (P + 1).

So, (P - 1) + P + (P + 1) = 102

3P = 102 => P = 34.

The lowest of the three = (P - 1) = 34 - 1 = 33.

Question sixty two. The Sum Of The Two Digits Of A Number Is 10. If The Number Is Subtracted From The Number Obtained By Reversing Its Digits, The Result Is 54. Find The Number?

Any  digit quantity may be written as (10P + Q), wherein P is the digit within the tens location and Q is the digit inside the devices vicinity.

P + Q = 10 ----- (1)

(10Q + P) - (10P + Q) = fifty four

nine(Q - P) = 54

(Q - P) = 6 ----- (2)

Solve (1) and (2) P = 2 and Q = 8

The required range is = 28

Question 63. The Sum Of The Present Ages Of Two Persons A And B Is 60. If The Age Of A Is Twice That Of B, Find The Sum Of Their Ages 5 Years Hence?

A + B = 60, A = 2B

2B + B = 60 => B = 20 then A = forty.

Five years, their a long time may be 45 and 25.

Sum of their ages = forty five + 25 = 70.

Question 64. The Tax On A Commodity Is Diminished By 20% But Its Consumption Is Increased By 10%. Find The Decrease Percent In The Revenue Derived From It?

a hundred * a hundred = 10000

eighty * one hundred ten = 8800

10000------- 1200

a hundred ------- ? = 12%.

Question sixty five. There Were Two Candidates In An Election. Winner Candidate Received 62% Of Votes And Won The Election By 288 Votes. Find The Number Of Votes Casted To The Winning Candidate?

W = 62%    L = 38%

sixty two% - 38% = 24%

24% -------- 288

62% -------- ? => 744.

Question 66. Find The 37.5% Of 976 =

37.Five % of 976

= 37.5/100 * 976 = 375/a thousand * 976 = three/eight * 976

= three * 122 = 366.

Question 67. 64 Is What Percent Of eighty?

Let x percentage of 80 be 64.

Eighty * x/100 = sixty four => x = (sixty four * one hundred)/80 => x = eighty.

Eighty% of 80 is 64.

Question 68. 3/20 Is What Percent Of 12/25?

Let the specified percentage be x%.

Three/20 = x% of 12/25 => three/20 = x/one hundred * 12/25

=> 12x = (300 * 25)/20 => x = (25 * 25)/20

=> x = 31.25%.

Question 69. Find The Roots Of The Quadratic Equation: 2x2 + 3x - 9 = 0?

2x2 + 6x - 3x - nine = 0

2x(x + 3) - three(x + 3) = 0

(x + 3)(2x - 3) = zero

=> x = -3 or x = three/2.

Question 70. If The Sides Of A Triangle Are 26 Cm, 24 Cm And 10 Cm, What Is Its Area?

The triangle with aspects 26 cm, 24 cm and 10 cm is right angled, in which the hypotenuse is 26 cm.

Area of the triangle = half * 24 * 10 = a hundred and twenty cm2.

Question seventy one. A Wire In The Form Of A Circle Of Radius three.5 M Is Bent In The Form Of A Rectangule, Whose Length And Breadth Are In The Ratio Of 6 : five. What Is The Area Of The Rectangle?

The circumference of the circle is equal to the permeter of the rectangle.

Let l = 6x and b = 5x 2(6x + 5x) = 2 * 22/7 * three.Five

=>  x = 1

Therefore l = 6 cm and b = 5 cm Area of the rectangle = 6 * 5 = 30 cm2.

Question seventy two. The Dimensions Of A Room Are 25 Feet * 15 Feet * 12 Feet. What Is The Cost Of White Washing The Four Walls Of The Room At Rs. 5 Per Square Feet If There Is One Door Of Dimensions 6 Feet * three Feet And Three Windows Of Dimensions four Feet * 3 Feet Each?

Area of the 4 partitions = 2h(l + b)

Since there are doorways and home windows, place of the partitions = 2 * 12 (15 + 25) - (6 * three) - 3(4 * 3) = 906 sq.Toes.

Total cost = 906 * 5 = Rs. 4530.

Question seventy three. If Two Dice Are Thrown Together, The Probability Of Getting An Even Number On One Die And An Odd Number On The Other Is -.

The wide variety of exhaustive outcomes is 36.

Let E be the occasion of having a fair quantity on one die and an peculiar quantity on the opposite.

Allow the event of having both each even or both extraordinary then  = 18/36 = half of

P(E) = 1 - 1/2 = half of.

Question 74. The Probability That A Speaks Truth Is 3/five And That Of B Speaking Truth Is four/7. What Is The Probability That They Agree In Stating The Same Fact?

If both agree stating the identical reality, either both of them talk fact of both talk false.

Probability = three/five * 4/7 + 2/5 * three/7

= 12/35 + 6/35 = 18/35. ## Top Courses ##### CodeIgniter ##### Internet of Things ##### JIRA ##### OrientDB ##### Selenium
