The pie chart given below shows the percentage of time taken by different processes in making a car.
If total time taken in engine and tyres is 127.5 hours, then what is the difference (in hours) in time taken by frame and glass respectively?
Total time taken in engine and tyres (in %) = 40+11 = 51%
Now, difference in time taken by frame and glass (in %) = 22-8 = 14%
According to ques, $$51\% \equiv 127.5$$
=> $$14\% \equiv \frac{127.5}{51}\times14$$
= $$2.5\times14=35$$ hours
=> Ans - (D)
