Answer 2

Answer:

What sum of money will amount to 900 in 4 years at 5%? A. 650 B. * 750 C. * 675 D. 3 775 A ​

Answer is ₹ 750

Step-by-step explanation:

As per formula

Principal = amount x 100/ 100 + (time *rate)

So, principal = 900*100/ 100 + (4*5)

= 90000 / 120

Principal = ₹ 750

Amount = principal + interest

900 = 750 - interest

So, 900-750 =150

Interest is 150

So, 750+150= 900

Answer is ₹ 750/-
