Question

Ramesh spend is 5/6 th part of monthly income if his annual saving is rs 624 find his annual income

Answer 1

per year he saves=624 rupees
In 1 month=624/12
In 1 month he save=52 rupees

He spend =5/6 of income
Let his total income is =X rupees
spend =5x/6 rupees

(suppose I total earn 10 rupees and spend 2/5 0f it so what I have remaining I have to subtract 10-2/5)

So
x-5x/6=52
LCM=6
X/6=52
X=52*6
X=312rupees

So in one month he earn =312 rupees
In 12 month=312*12=3744 rupees
