SSC GD 2024 PYQ — Question 41

The correct answer is option 3 i.e. Rs 570.

Given that, difference in simple ineterest = Rs 57

Rate = 10%

SI = ${P \times R \times T} \over 100$

where P, R and T are sum of money, rate and time period respectively.

Let the sum of money be Rs P.

According to the given question,

${P \times 10 \times 8} \over 100$ - ${P \times 10 \times 7} \over 100$ = 57

⇒ 10P = 5700

⇒ P = 570 

Hence the sum of money is Rs 570.
