Question

Mr.Rane gives 0.025 part of her salary as pocket money to her son vino every month. vino spends 0.8 part of his money and saves the rest. if he has 277.50 in three months, how much does he earn in a month

Answer 1

let the salery be x
pocket money be y
money remaining be z

y = 0.025 * x
z = 0.2* 0.025 * x
z = 0.0005x

he saves 277.5 in 3 months, so in one month 277.5/3 = 92.5
92.5 = 0.005 x
x = 18500

Therefore salary is 18500
