Question

A man had ₹ 36000, 1/3rd of it he invested in shares, 3/10th of the remainder he donated to a charity and 3/4th of the remainder spent on food. How much money is left with him?

Answer 1

First we have to lcm the denominator

LCM of the denominator is 60.

so $\frac{1}{3}$ * $\frac{20}{20}$ = $\frac{20}{60}$

$\frac{3}{10}$ * $\frac{6}{6}$ = $\frac{18}{60}$

$\frac{3}{4}$ * $\frac{15}{15}$ = $\frac{45}{60}$

Money left with him = (60/60 - total expense(including everything))*₹36,000

= 60/60 - 83/60

= $\frac{-23}{60}$ * ₹36,000

= -₹13,800.00
