If the number be N, then
N × 75 + 75 = N 100 ⇒ 3N + 75 = N 4 ⇒ N - 3N + 75 4
Correct Option: C
If the number be N, then
N × 75 + 75 = N 100 ⇒ 3N + 75 = N 4 ⇒ N - 3N + 75 4 ⇒ N = 75 4
⇒ N = 4 × 75 = 300∴ 40% of 300 = 300 × 40 = 120 100

Let the numbers be p and q and p > q.
According to the question,6 1 % of p = 8 1 % of q 2 2 ⇒ 13 % of p = 17 % of q 2 2
⇒ 13p = 17q⇒ p = 17 q 13 ∴ 17 q – q = 1660 13
Correct Option: B
Let the numbers be p and q and p > q.
According to the question,6 1 % of p = 8 1 % of q 2 2 ⇒ 13 % of p = 17 % of q 2 2
⇒ 13p = 17q⇒ p = 17 q 13 ∴ 17 q – q = 1660 13 ⇒ 17q – 13q = 1660 13
⇒ 4q = 1660 × 13⇒ q = 1660 × 13 = 5395 4
