ANSWER KEYS and SOLUTIONS:

Solutions of the Above Questions with Explanation

Solution 1: 4)

Let total number of votes be ‘100x’

So, number of votes ‘A’ got = 100x X 0.3 = ’30x’

Number of votes ‘B’ got = 100x X 0.25 = ’25x’

So, number of votes ‘C’ got = 100x – (30x + 25x) = ’45x’

ATQ:

45x – 30x = 2400

Or, 15x = 2400

So, x = 160

So, number of votes ‘B’ got = 160 X 25 = 4,000

Hence, option d.

Solution 2: 2)

Quantity of non-rotten apples in the truck = 730 X 0.80 = 584 kg

Hence, option b.

Solution 3: 3)

Let the third number be ’20x’.

So, one of the numbers = 20x X 1.2 = ’24x’

And, the other number = 20x X 1.25 = ’25x’

So, required ratio = 24x:25x = 24:25

Hence, option c.

Solution 4: 1)

Number of votes which were cast = 1500 X 0.72 = 1080

So, number of valid votes which were cast = 1080 X 0.8 = 864

Hence, option a.

Solution 5: 4)

Let the initial price of the sugar be Rs. ‘4x’ per kg

So, initial quantity of bought = 600 ÷ 4x = (150/x) kg

So, new price of sugar = 4x X 0.75 = Rs. ‘3x’ per kg

ATQ;

(600 ÷ 3x) – 12.5 = (150/x)

Or, (200/x) – 12.5 = (150/x)

Or, 12.5x = 200 – 150

Or, 12.5x = 50

So, x = 4

So, initial price of the sugar = 4 X 4 = Rs. 16 per kg

Alternate solution

Ratio of initial and new price = 4:3

So, ratio of initial consumption and new consumption = (1/4):(1/3) = 3:4

So, required answer = {600/(3 X 12.5)} = Rs. 16

Hence, option d.

Solution 6: 1)

Let the present age of Ram be ‘5x’ years

So, present age of Raman = 5x X 1.4 = ‘7x’ years

ATQ;

7x + 5x = 36

Or, 12x = 36

So, x = 3

So, required difference = 7x – 5x = 2x = 2 X 3 = 6 years

Hence, option a.

Solution 7: 4)

ATQ;

300 + y = x

Also,

0.4 X x = 100 + 0.6 X y

Or, 0.4 X (300 + y) = 100 + 0.6y

Or, 120 + 0.4y = 100 + 0.6y

Or, 20 = 0.2y

So, y = 100

So, x = 300 + 100 = 400

So, required sum = 400 + 100 = 500

Hence, option d.

Solution 8: 3)

Marks scored by student = 250 X 0.44 = 110

So, passing marks = 110 + 16 = 126

So, passing percentage = (126/250) X 100 = 50.4%

Hence, option c.

Solution 9: 4)

Number of adults in the village = 56000 – 56000 X 0.35 = 36400

Number of registered voters in the village = 36400 X 0.8 = 29120

Hence, option d.

Solution 10: 1)

Remaining number of red balls in the box = 

Remaining number of pink balls in the box = 

Now, total number of balls in the box = (200 + 50 + 50) = 300

Required percentage = 

Hence, option a.
