Originally, let the number of boys and girls in the college be 7x and 8x respectively. Their increased number is (120% of 7x) and (110% of 8x). (120*7x)/100 and (110*8x)/100 42x/5 and 44x/5 The required ration = 42x/5: 44x/5 = 21: 22 |

Total investment = Rs. (120 * 80 + 280 + (40/100) * 120 + 72).
= Rs. (9600 + 280+48 + 72) = Rs, 10000.
Sell price of 120 reams = 108% of Rs. 10000 = Rs. 10800.
Sell Price per ream = Rs. [10800/120] = Rs. 90.

Let their present ages be s and a respectively.
Then we have s + 5 = 2(a-5) --------(1)
a + 5 = s –5 ----------(2)
By solved the two educations we get s
= 35 and a = 25. if x years back Sangeeta was twice as old as Anugeeta, we have 35 – x =2(25-x)
⇒ x = 15

Solution :
If we consider a = 2, then a + 9d = 38 , 9d = 36, -> d =4 , therefore a +4d = 2 + 4 x 4 = 18 .
