Question

if rs 5600 amount to rs 6678 in 3 1/2 years, what will rs 9400 amount to in 5 1/4 years at the same rate precent per annum simple interest​

Answer 1

Step-by-step explanation:

Principal = 5600

Amount = 6678

So, S.I = A - P

= ₹1078

Now, S.I = P*R*T/100

T = 7/2 years.

1078 = 5600*R*7/2*100

R = 1078 * 2 /7*56

R = 154 * 2/56

R = 154 / 28

R = 5.5%

Now, new P = 9400

T = 21/4 years

R = 5.5%

So S.I = 9400 * 5.5 * 5.25 /100

S.I = 94 * 28.875

S.I = 2714.25

A = P + S.I

A = 9400 + 2714.25

A = 12114.25
