Question

Manu invested an amount of Rs. 14800 at the rate of 7% per annum. After how many years will she obtain a simple interest of Rs.15800?

A) 16.75 yrs B) 15.25 yrs C) 14 yrs D) 13.5 yrs

Answer 1

Answer:

B)15.25 YRS

Step-by-step explanation:

HERE

PRINCIPAL = 14800

RATE =7% P.A

TIME=?

LET THE TIME BE x

ATP,

14800 X 7 X x / 100 = 15800

=>148 X 7 X x = 15800

=>1036x =15800

=>x=15800 / 1036

=>x=15. 25 YRS

Answer 2

Sᴏʟᴜᴛɪᴏɴ :-

→ Principal = Amount invested = Rs.14800

→ Rate = 7% per Annum.

→ Time = Let T years.

→ Simple interest = Rs.15800 .

Putting values in SI formula now, we get,

→ SI = (P * R * T)/100

→ 15800 = (14800 * 7 * T)/100

→ (15800 * 100) = (14800 * 7 * T)

→ T = (15800 * 100) / (14800 * 7)

→ T = 15800 / (148 * 7)

→ T ≈ 15.25 years. (Ans.)

Hence, Required Time period is 15.25 years.

Direct :-

→ Time = (Simple interest * 100) / (Principal * Rate)

→ Time = (15800 * 100) / (14800 * 7)

→ T = 15800 / (148 * 7)

→ T ≈ 15.25 years. (Ans.)
