Question 53

The average age of a group of 12 students is 20years. If 4 more students join the group, the average age increases by 1 year. The average age of the new students is?
Show explanation Expand Question
Initial total age = \(12 \times 20 = 240\).
New average = 21 for 16 students:
\(16 \times 21 = 336\).
Total age of new students = \(336 - 240 = 96\).
Average age of new students = \(\frac{96}{4} = 24\).

Question 54

( 1 / 4 )3 + (3/4)3 + 3(1/4)(3/4)(1/4 + 3/4) =?
Show explanation Expand Question
Recognise the identity:\[(a + b)^3 = a^3 + b^3 + 3ab(a + b)\]Let \(a = \frac{1}{4}\), \(b = \frac{3}{4}\).
Then expression becomes:\[(a + b)^3 = \left(\frac{1}{4} + \frac{3}{4}\right)^3 = 1^3 = 1\].

There are---------- seconds in sixty (60) days
Show explanation Expand Question
Number of seconds in one day = \(24 \times 60 \times 60 = 86400\).
For 60 days:\[86400 \times 60 = 5,184,000\]This gives the total number of seconds in sixty days.

Question 59

Three fat ladies stood under an umbrella but none of them got wet. Why didn't any of them get wet?
Show explanation Expand Question
The wording in the options appears incomplete, but the logical interpretation of the question remains the same. If none of the ladies got wet despite standing under an umbrella, the only reasonable explanation is that it was not raining. Without rain, there is no condition that would cause them to get wet.

Question 60

If during a one-year period, the dividend paid on a certain share of stock was equal to 8 percent of the par value of the stock, then the dividend paid was fraction of the par value of the stock?
Show explanation Expand Question
The dividend is given as 8 percent of the par value.
Convert percentage to fraction:\[8\% = \frac{8}{100}\]Simplify the fraction:\[\frac{8}{100} = \frac{2}{25}\]This represents the fraction of the par value paid as dividend.
