A landowner increased the length and breadth of a rectangular plot by 10% and 20% respectively. Find the percentage change in the cost of the plot.
Answer: (a)

In an election between two candidates, 75% of the voters cast their votes, out of which 2% of the votes were declared invalid. A candidate got 9261 votes which were 75% of total valid votes. Find the total number of votes enrolled in that election.
Answer: (a)
Let the total number of votes enrolled be x.
Then, Number of votes cast = 75% of x.
Valid votes = 98% of (75% of x).
∴ 75% of [98% of (75% of x)] = 9261
$(75/100 × 98/100 × 75/100 × x) = 9261$
⇒$x = ({9261 × 100 × 100 × 100}/{75 × 98 × 75}) = 16800.$
Deepa decided to donate 8% of her salary to an orphanage, On the day of donation she changed her mind and donated Rs. 2240 which was 80% of what she had decided earlier. How much is Deepa's salary?

Let the salary of Deepa be Rs. x.
Then, 80% of 8% of x = 2240
$80/100 × 8/100 × x = 2240$
$x = {2240 × 100 × 100}/{80 × 8}$ = 35000
Hence, the salary of Deepa = Rs. 35000
