3)	Rs. 698	4)	Rs. 700
5)	None of these

Answer : Rs. 698
Explanation :

S.I. for 1 year = Rs. (854 - 815) = Rs. 39.

S.I. for 3 years = Rs.(39 x 3) = Rs. 117.

Principal = Rs. (815 - 117) = Rs. 698.

Q25.	A sum of Rs. 1550 is lent out into two parts, one at 8% and another one at 6%. If the total annual income is Rs. 106, find the money lent at each rate ?

1)	Rs. 800	2)	Rs. 900
3)	Rs. 1100	4)	Rs. 870
5)	None of these

Answer : Rs. 900
Explanation :

Let the sum lent at 8% be Rs. x and that at 6% be

Rs. (1550 - x).

or (X x 8 x 1/100 ) + [ {(1500- X) x 6 x 1}/ 100 ] = 106

or 8 x + 9300 - 6 x = 10600

or 2 x = 1300

or x = 650

Money lent at 8% = Rs.650.

Money lent at 6% = Rs(1550 - 650) = Rs. 900

Q26.	A sum was put at S.I. at certain rate for 5 years. Had it been put at 4% higher rate, it would have fetched Rs. 60 more. What was the sum ?

1)	Rs.280	2)	Rs.300
3)	Rs.320	4)	Rs.400
5)	None of these

Answer : Rs.300
Explanation :

Let Principal =P, Rate of Interest = R

Given, T = 5 So, (P x 5 x R) / 100

Now new rate of interest =( R+ 4) %

So, S.I. = {P x 5 x (R+ 5%) } / 100

Then, {P x 5 x (R+ 5%) } / 100 - (P x 5 x R) / 100 = 60

or P /60 = 5 or P= Rs. 300
