# What will be The Same Principle in 5 years? If

Answered

Rs 6000 become Rs 7200 in 4 years at a certain rate of simple interest. If the rate becomes 1.5 times of itself, the amount of the same principal in 5 years will be:

- Rs 8000
- Rs 8250
- Rs 9000
- Rs.9250

Best answer

**Answer: (2) Rs.8250**

**Explanation:-**

**Given-**

Principal = Rs.6000, Amount = Rs.7200, Time = 4 years & Rate = ?

Simple Interest = 7220 – 6000= Rs.1200

**Formula-**

**Simple Interest = P x R x T/100**

**Where, P = principal , R = rate, & T = time.
**Then, 1200 = 6000 x R x 4/100

12 = 60 x R /25

R = 5 %

If rate become 1.5 times

Then, Rate = 5 x 1.5

= 7.5 % = 15/2 %

Then, the simple Interest for 5 years,

S I = 6000 x 15 x 5/2 x 100

= 30 x 75

= 2250

Amount = 6000 + 2250

= Rs.8250

Hence, the answer is (2) Rs.8250.
