| 1) | Rs.3794 | 2) | Rs.3714 |
| 3) | Rs.4612 | 4) | Rs.4634 |
| 5) | None of these | ||
Answer : Rs.4634
Explanation :
Explanation :
Let P = Rs.100
Simple Interest = Rs. 80 ( ∵ 80% increase is due to the simple interest)
Rate of interest = (100×SI)/PT=(100×80)/100×8 =10% per annum
Now let's find out the compound interest of Rs. 14,000 after 3 years at 10%
P = Rs.14000 T = 3 years and R = 10%
Amount after 3 years = P(1+R/100)T = 14000 (1+10/100)3= Rs.18634
So, C.I = Rs.18634 - Rs.14000 = Rs.4634
