A company purchased raw material worth 1/4 of it capital, 1/10 of the remaining is spent on machinery. How much fraction of the capital was left with the company after its expenditures on raw material and machinery?  Choose the correct choice from the following options:  A) 1/5  B) 2/8  C) 5/9  D) 27/40  E) 15/30
The amount spent by the company on raw material is 1/4, so remaining is 3/4.   1/10 of the remaining is spent on machinery, 1/10*3/4=3/40   Total amount spent on raw material and machinery is 1/4+3/40   To make the denominator common we use 40, so 1/4 is 10/40   10/40+3/40=13/40 is spent on raw material and machinery   Remaining 27/40 is left with the company   Answer is 27/40
