A man spends 2/5 of his salary on house rent,3/10 of his salary on food and 1/8 of his salary on conveyence. If he has Rs.1400 left with him,find his expenditure on food and conveyence.

Answer»

Part of salary left=1-(2/5+3/10+1/8) 

Let the monthly salary be Rs.x 

Then, 7/40 of x=1400 

X=(1400*40/7) =8600 

Expenditure on food=Rs.(3/10*800)=Rs.2400 

Expenditure on conveyence=Rs.(1/8*8000)=Rs.1000
