Answer 2

Answer:

Interest = 4,270

Total amount Rita has to pay = Rs . 8,470

Explanation :

Given that

Principal Amount ( P ) = 4,200

Rate of Interest ( r ) = 5% = 5 / 100 =0.05

Time ( t ) = 4 months

Time ( t ) = 4 / 12 = 1 / 3 = 0.3333 years

Interest = ?

Interest = P ( 1 + rt )

I = 4,200 ( 1 + 0.05 × 0.3333 )

I = 4,200 ( 1.016665 )

I = 4,270

Total Amount that Ritu haa to pay = 4,200 ( P ) + 4,270 ( I ) = 8,470
