Q2. Ramesh spends 5/6th part of his monthly income. if his annual saving is Rs.624 find his annual income.

then, its 4/5 is 4/5x

ATQ. 4/5x=1680

4x = 1680*5

x= 8400/4 = Rs.2100

now half of the real estate = 2100/2 = Rs.1050

Q2. expenditure by ramesh=5/6th part of income

saving by ramesh=6/6-5/6=1/6th part of income
