Answer 1

Answer:

The answer is Rs 10,400

Amount = Rs 10,400

Step-by-step explanation:

SI = $\frac{PRT}{100}$

2400 = P× 10×3 ÷ 100

2400 = $\frac{30P}{100}$

P = 2400 × 100 ÷ 30

P = $\frac{240000}{30}$

P = 8000

Amount = Principal + Interest

Amount= 8000 + 2400 = Rs 10,400

24×10×3

= 24×30 or 240×3
