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

$(75/100 × 98/100 × 75/100 × x) = 9261$

⇒$x = ({9261 × 100 × 100 × 100}/{75 × 98 × 75}) = 16800.$

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
