Step-by-step explanation:
1.
The Principal Amount is Rs. 1250 and the final amount after one year is Rs. 1950. Hence the interest earned
I = Final - principal amount
= 1950 - 1250
= Rs. 700
Now Interest I = P x R x T /100
where
I = interest = 700
P = Principal Amount = 1250
R = Rate of interest = 16%
T = time = to find
Therefore, from data
700 = 1250 x 16 x T /100
700 = 20,000 x T /100
700 = 200 x T
T = 700/200
= 3.5 years.
Therefore time = 3.5 years.
2.
Principal Amount = Rs. 6540
Final Amount = Rs. 8447.5
Interest earned = Rs. (8447.5 - 6540)
= Rs.1907.5
Now, I = P x R x T /100
1907.5 = 6540 x 12.5 x T /100
1907.5 = 81,750 x T /100
T = 1907.5 x 100 / 81750
T = 2.33 years
= 2 years and 4 months.
