Question

at what rate of interest per annum should Mohan invest if you want to grow his rupees 2500 to rupees 4000 in 5 years​

Answer 1

Answer:

12%

Step-by-step explanation:

P = 2500

A = 4000

S.I.= A - P = 4000-2500= 1500

R% = 1500× 100 / 2500 × 5

= 12%

Answer 2

Answer:

12%

Step-by-step explanation:

Since we are not provided whether the money is invested at simple interest or at compound interest, we will assume the money to be invested at simple interest.

Hence,

Principal (P) = 2500 Amount (A) = = 4000 Time Period (T) = 5 years Let the rate of interest be R.

Since,

Amount = Principal + Simple Interest 4000 = 2500 + Simple Interest

Simple Interest=4000 - 2500= 1500

Now we know that,

Simple Interest = ( P* R * T) / 100

1500 (2500 * R * 5 ) / 100

1500 12500 R / 100

1500 = 125 R R = 1500/125

R = 12 %

Hence,

Rate of interest = R = 12 %
