If 64 added in a number then the number becomes 157\(\frac{1}{7}\)% of itself. Find the number.
Answer & explanation
Correct answer: option 3
157\(\frac{1}{7}\) % = 100 % + 57\(\frac{1}{7}\)%
ATQ, 57\(\frac{1}{7}\)% = 64
57\(\frac{1}{7}\)% = \(\frac{4}{7}\)
Here, ATQ,
4R = added number = 64
1R = 16
7R = original number = 7 x 16 = 112
