21) Sahil took a loan for 6 years at the rate of 5% per annum on Simple Interest, If the total interest paid was Rs. 1230, the principal wa

• 1) 4100
• 2) 4200
• 3) 4300
• 4) 4400
Ans.   A
Explanation :
\begin{aligned} \text{S.I.} = \frac{P*R*T}{100} \=> P = \frac{S.I. * 100}{R*T} \end{aligned} By applying above formula we can easily solve this question, as we are already having the simple interest. \begin{aligned} => P = \frac{1230 * 100}{6*5} \=> P = 4100 \end{aligned}

22) There was simple interest of Rs. 4016.25 on a principal amount at the rate of 9%p.a. in 5 years. Find the principal amou

• 1) Rs 7925
• 2) Rs 8925
• 3) Rs 7926
• 4) Rs 7925
Ans.   B
Explanation :
\begin{aligned} P = \frac{S.I. * 100}{R*T} \end{aligned} So by putting values from our question we can get the answer \begin{aligned} P = \frac{4016.25 * 100}{9*5} \ = 8925 \end{aligned}

23) Find the rate at Simple interest, at which a sum becomes four times of itself in 15 year

• 1) 10%
• 2) 20%
• 3) 30%
• 4) 40%
Ans.   B
Explanation :
Let sum be x and rate be r% then, (x*r*15)/100 = 3x [important to note here is that simple interest will be 3x not 4x, beause 3x+x = 4x] => r = 20%
