SSC Selection Post 2022 PYQ — Question 70

The correct answer is option 2 i.e. 2.

Amount(A) = Principal(P) + Interest

⇒ A = 50000 + 7245 = 57245

⇒ A = P(1 + $R\over100$)^T

here, T = Time, R = Rate

⇒ 57245 = 50000(1 + $7\over100$)^T

⇒ $57245\over50000$ = (1 + $7\over100$)^T

Go through the options

Time = 2

⇒ $57245\over50000$ = (1 + $7\over100$)²

⇒ $107\over100$ = (1 + $7\over100$)

⇒ $107\over100$ = $107\over100$ (satisfy)
