Question : The difference between Simple and Compound Interest (compounded annually) on Rs. 40,000 for 3 years at 8% per annum is:
Option 1: Rs. 684.32
Option 2: Rs. 788.48
Option 3: Rs. 784.58
Option 4: Rs. 4,000
Correct Answer: Rs. 788.48
Solution : The formula for the difference between Compound Interest(CI) and Simple Interest(SI) for 3 years is given by: $CI-SI=\frac{PR^{2}(300+R)}{100^{3}}$, where $P$ is principal and $R$ is rate of interest per annum compounded annually. ⇒ $CI-SI=\frac{40000\times8^{2}\times(300+8)}{100^{3}}$ ⇒ $CI-SI=\frac{788480000}{1000000}$ $\therefore CI-SI=788.48$ Hence, the correct answer is Rs.
Question : The average height of 30 boys out of a class of 50 is 160 cm. If the average height of the remaining boys is 165 cm, the average height of the whole class (in cm) is:
Option 1: 161
Option 2: 162
Option 3: 163
Option 4: 164
Correct Answer: 162
Solution : Given: The average height of 30 boys out of a class of 50 is 160 cm. Average height of remaining boys = 165 cm Formula Used: $\text{Average} = \frac{\text{Sum of the heights of all the students}}{\text{Number of students}}$ Calculation: Total height of 30 boys $=

Question : A and B were partners in a firm sharing profits and losses in the ratio of equally . With effect from 1st January 2019 they agreed to share profits and losses 2:1 Individual partner’s gain or sacrifice due to change in the ratio will be :
Option 1: Gain by $A \frac{1}{6}$; Sacrifice by $B \frac{1}{6}$
Option 2: Gain by $A \frac{1}{2}$; Sacrifice by $B \frac{1}{2}$
Option 3: Sacrifice by $A \frac{1}{2}$; Gain by $B \frac{1}{2}$
Option 4: Sacrifice by $A \frac{1}{2}$; Gain by $B \frac{1}{2}$
Correct Answer: Gain by $A \frac{1}{6}$; Sacrifice by $B \frac{1}{6}$
Solution : Answer = Gain by $A \frac{1}{6}$; Sacrifice by $B \frac{1}{6}$
Sacrificing Ratio = old ratio - new ratio
A = 1/2 - 2/3 = 3-4/6 = -1/6 (gain)
B = 1/2 - 1/3 = 3-2/6 = 1/6 (sacrifice)
