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 conveyance . If he has Tk. 1400 left with him,find his expenditure on food and conveyance .

A 1000 

B 2000 

C 3000 

D 5000 

Solution

Correct Answer: Option A

part of salary left = 1- \((\frac{2}{5} + \frac{3}{{10}} + \frac{1}{8}) = \frac{7}{{40}}\) 

Let the monthly salary be Tk. x 

Then, 7/40 of x = 1400 

 x = \((1400 \times \frac{{40}}{7})\) = 8600 so, Expenditure on conveyance = Tk. \((\frac{1}{8} \times 8000)\) = Tk. 1000
