Question

sushma gives 0.025 part of her salary as pocket money to her son every month .He spends 0.8 part of her pocket money and saves the rest .If he saves Rs555in 6 months ,find the monthly salary of sushma?

Answer 1

Given :

Part of salary given as pocket money every month = 0.025

Part of pocket money spend = 0.8

Part of money saves = 1 - 0.8 = 0.2

Amount of money saves in 6 months = Rs 555

To Find :

The monthly salary

Solution :

Let The money given to son = Rs x

Let The salary amount = Rs y

∵ Amount of money saves in 6 months = Rs 555

∴ Amount of money saves in 1 month = Rs $\dfrac{555}{6}$  = Rs 92.5

Again

Part of money saves = 0.2 of money given

Or, Rs 92.5 = 0.2 × x

Or,  x = $\dfrac{92.5}{0.2}$ = Rs 462.5

So, The money given to son =  x = Rs 462.5

Again

∵ Part of salary given as pocket money every month = 0.025 of total salary

Or,                                                                                 y = 40 × x

Or,                                                                                 y =  40 ×  Rs 462.5

∴                                                                                    y = Rs 18500

Hence, The monthly salary of Sushma is Rs 18500 . Answer
