Question
A and B invested Rs.3000 and Rs.6000 in a business
respectively and after 5 months B withdrawn 50% of his initial investment and again after 5 months he reinvested 50% of amount of what he withdrawn. After a year they got total profit of Rs.35325, find the profit share of A (in Rs).Solution
Ratio of profit share between A and B, => 3000 x 12 : [(6000 x 5) + (3000 x 5) + (4500 x 2) => 36000 : (30000 + 15000 + 9000) => 36000 : 54000 => 2:3 Profit share of A = (35325/5) x 2 = Rs.14130

In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. x2 – ...
I.8(x+3)+ 8(-x)=72
II. 5(y+5)+ 5(-x)=150
