30% of a number when subtracted from 91, gives the number itself. Find the number.

A. 60

B. 65

C. 75

D. 70

E. None of these

Answer: Option D

Solution (By Examveda Team)

Let the number be x
According to the question,
91 - $$\frac{{30{\text{x}}}}{{100}}$$ = x
9100 - 30x = 100x
Or, 9100 = 130x
Or, x = $$\frac{{9100}}{{130}}$$
Hence, x = 70
