Question : A sum of money is paid back in two annual instalments of Rs. 17,640 each, allowing 5% Compound interest compounded annually. The sum borrowed was:
Option 1: Rs. 32,800
Option 2: Rs. 32,200
Option 3: Rs. 32,000
Option 4: Rs. 32,400
Correct Answer: Rs. 32,800
Solution : Given: Installment = Rs. 17,640 Rate = 5% Total installments = 2 1st instalment includes 5% interest on the given instalment. Required sum borrowed = 1st installment + 2nd installment $P(1+\frac{5}{100})^2= 17640(1+\frac{5}{100})+17640$ ⇒ $P(\frac{105}{100})^2 = 17640(1+\frac{5}{100}+1)$ ⇒ $P = 17640×\frac{205}{100}×\frac{100}{105}×\frac{100}{105}$ So, P = 32800

Question : The volume of a conical tent is 1232 m3 and the area of its base is 154 sq m. Find the length of the canvas required to build the tent, if the canvas is 2 m in width. (Take $\pi=\frac{22}{7}$)
Option 1: 270 m
Option 2: 272 m
Option 3: 276 m
Option 4: 275 m
Correct Answer: 275 m
Solution : Let the radius be $r$ and the height be $h$. Area of the base = 154 sq m ⇒ $\pi r^2$ = 154 $\therefore r$ = 7 m Volume of cone = $\frac{1}{3}\pi r^2 h$ ⇒ $1232 =\frac{1}{3}×\frac{22}{7}×7×7×h$ $\therefore h = 24$ m Slant
Question : A, B, and C run simultaneously, starting from a point, around a circular track of length 1200 m, at respective speeds of 2 m/s, 4 m/s, and 6 m/s.
