Question 1. H.C.F. Of 3240, 3600 And A Third Number Is 36 And Their L.C.M. Is 24x 35 X fifty two X 72 The Third Number Is?
Answer :
3240 = 23x 34x five; 3600 = 24x32 x 52; H.C.F. = 36 = 22x32
Since H.C.F. Is the manufactured from lowest powers of commonplace factors,
so the 0.33 quantity have to have (22x32) as its elements
Since L.C.M. Is the manufactured from highest powers of not unusual high factors,
so the 0.33 variety ought to have 35and 72 as its elements.
Third number = 22x35x72.
Question 2. The Largest Four ? Digit Number Which When Divided By four, 7 Or thirteen Leaves A Remainder Of three In Each Case, Is?
Answer :
Greatest wide variety of 4 digits is 9999, L.C.M. Of four, 7 and 13 = 364
On dividing 9999 by way of 364, the rest received is 171.
Greatest number of 4 digits divisible by way of 4, 7 and 13 = (9999 ? 171) = 9828
Hence, required quantity = (9828 + 3) = 9831.

Question eight. The H.C.F. And L.C.M. Of Two Numbers Are 11 And 385 Respectively. If One Number Lies Between seventy five And one hundred twenty five, Then That Number Is?
Answer :
Product of numbers = eleven x 385 = 4235.
Let the numbers be 11a and 11b. Then 11a x 11b = 4235 ab = 35
Now, co-primes with product 35 are (1, 35) and (five, 7).
So, the numbers are (eleven x 1, 11 x 35) and (11 x 5, 11 x 7).
Since one wide variety lies between 75 and one hundred twenty five, the appropriate pair is (fifty five, 77)
Hence, required variety = seventy seven.

Question 19. A Girl Bought A Book For Rs.450 And Sold It At 20% Profit. By Using That Amount She Bought Another Book And Sold It At five% Loss. Then Overall Profit Amount Is?
Answer :
Given
Cost Price of 1st ebook = Rs.450.
Profit % on promoting 1st e-book = 20%
Selling charge of 1st e-book = (a hundred + Profit%) / 100 * C.P
= (one hundred + 20) / one hundred * 450
= (one hundred twenty / 100) * 450
= 12 * forty five
= 540 Rs.
Cost fee of 2nd ebook = Rs.540
Loss % on promoting 2nd e-book = 5%
Selling price of 2nd book = (100 - Loss%) / a hundred * C.P
= (a hundred - five) / one hundred * 540
= (ninety five / a hundred) * 540
= 513 Rs.

= Rs.513 - Rs.450
= Rs. 63.
Question 20. A Shopkeeper Buys Bananas At 15 For Rs 12 And Sells At 12 For Rs.15. Find His Gain Or Loss Percent?
Answer :
Given, the C.P of 15 bananas = Rs. 12
=> C.P of 1 banana = Rs. 12/15
=> C.P of 12 bananas = Rs. (12 /15)* 12
= Rs. A hundred and forty four/15
= Rs. Forty eight/ 5
Thus,C.P of 12 bananas = Rs. Forty eight/ 5
Given,S,P of 12 bananas = Rs. 15
Gain = (S.P - C.P)of 12 bananas
= 15- (48/five)
= (seventy five- forty eight) / 5
= 27/ 5
=>Gain = Rs. 27/ five
Percentage Gain = (Gain/C.P of 12 bananas) * 100%
= (27/5) / (48/5) * a hundred%
= (27/forty eight) * one hundred%
= fifty six.25%
Thus,Gain % = 56.25%.

Question 22. Arjun Bought A T.V With 20% Discount On The Labelled Price. Had He Bought It With 25% Discount, He Would Have Saved Rs. 500. At What Price Did He Buy The T.V?
Answer :
Let labeled charge became one hundred.
Arjun sold T.V with 20% cut price, then
Cost rate of the T.V =classified price - 20% oflabeled rate
= one hundred - (20% of a hundred)
= eighty Rs.
If Arjunbought it at 25% bargain, then
Cost charge of the T.V =a hundred - 25% of 100
= seventy five Rs.
Given, If Arjun bought T.V with 25% cut price he might have stored Rs.500.
So, Difference among Cost fee for 20% and 25% discount = 500
=> eighty - 75 = 500
=> 5 parts = 500
=> 1 component = 500/5
=>1 element = 100
Then, the real Cost fee of the T.V =eighty components = 100 *eighty = 8000.
Correct Answer is Rs. 8000.
