Question

Sandeep saves 30% of his salary and spends the remaining. out of his total saving, he invests 40% in lic policy, 35% in hdfc and the remaining on the other. if the difference between the amount invested in lic and others is rs135, what is his salary?

Answer 1

Let the salary be     = x

Saved                     = 30% of x = 0.3x

Invested in LIC       = 40% of saving = 40% of 0.3x = 0.4*0.3x

Invested in HDFC  = 35% of saving = 35% of 0.3x = 0.35*0.3x

Others                    = 25% of saving = 25% of 0.3x = 0.25*0.3x

According to the question,

amount invested in LIC - amount invested in others = 135

0.4*0.3x - 0.25*0.3x = 135

0.3x(0.4 - 0.25) = 135

0.3x*0.15 = 135

x = 135/0.3*0.15

x = 3000

Therefore, salary = Rs 3000/
