Answer 2

Answer:

28000

Step-by-step explanation:

let sum is 100

for 1st year

S.I

(100*12*1)/100 = 12

C.I

(100*12*1)/100 = 12

for second year

S.I.

(100*12*1)/100 = 12

C.I

(112*12*1)/100 = 13.44 (for C.I. principal add intrest for next year principal )

for next 3 months

S.I

(100*3*1)/100 = 3

C.I

(125.44*3*1)/100 = 3.76

total S.I = 12+12+3 = 27

total C.I = 12+13.44 +3.76 =29.20

difference between S.I and C.I = 2.20

in question difference is 616

when sum is 100 then difference is 2.20

when sum is x the. difference is 616

then

x = (616*100)/2.20

x = 28000 rupees
