Sushma gives 0.025 part of her salary as pocket money to her son every month. He spends 0.8 part of pocket money and saves the rest. If he saves Rs 555 in 6 months, find the monthly salary of Sushma/

let the salary of Sushma be Rs. x

pocket money given to her son = 0.025 x.

since he spends 0.8 part of the pocket money.

therefore spend money by son =

therefore saved money in 1 month =

saved money in 6 month =

therefore

thus the salary of Sushma is Rs. 18500.

hope this helps you.

cheers!!
