Question 10 of 20
10. Question
What value should come in place of question mark (?) in the following questions?
3 5/8 + 6 1/2 – 5 1/8 = x – 5 ¼
Correct
Answer b
Explanation:
3 5/8 + 6 1/2 – 5 1/8 + 5 ¼ = x
(3 + 6 – 5 + 5)(5/8 + ½ – 1/8 + ¼) = x
X = 9 [(5 + 4 – 1 + 2)/8]
X = 9 (10/8) = 9 (5/4)
X = 10 ¼
Incorrect
Answer b
Explanation:
3 5/8 + 6 1/2 – 5 1/8 + 5 ¼ = x
(3 + 6 – 5 + 5)(5/8 + ½ – 1/8 + ¼) = x
X = 9 [(5 + 4 – 1 + 2)/8]
X = 9 (10/8) = 9 (5/4)
X = 10 ¼

Question 13 of 20
13. Question
The population of a town before three years was 44000. In first year it increased by 15%, in the second year again increased by 20% and in the third year decreased by 10%. Find the difference between present population of the town and the population of the town before three years?
Correct
Answer d
Explanation:
Present population of the town
= (44000) x (115/100) x (120/100) x (90/100)
= 54648
Required difference = 54648 – 44000 = 10648
Incorrect
Answer d
Explanation:
Present population of the town
= (44000) x (115/100) x (120/100) x (90/100)
= 54648
Required difference = 54648 – 44000 = 10648
Question 14 of 20
14. Question
Ratio of the ages of Ram and Shyam before five years was 5:3, ratio of their ages after five years will be 3:2. Manoj is five years older than Shyam. What is the present age of Manoj?
Correct
Answer d
Explanation:
Let five years ago, ages of Ram and Shyam were 5x and 3x respectively.
According to the question,
(5x + 10)/(3x + 10) = 3/2
=> 10x + 20 = 9x + 30
=> x = 10
Present age of Shyam = 3x = 3 * 10 + 5= 35
Present age of Manoj = 35 + 5 = 40 years
Incorrect
Answer d
Explanation:
Let five years ago, ages of Ram and Shyam were 5x and 3x respectively.
According to the question,
(5x + 10)/(3x + 10) = 3/2
=> 10x + 20 = 9x + 30
=> x = 10
Present age of Shyam = 3x = 3 * 10 + 5= 35
Present age of Manoj = 35 + 5 = 40 years
Question 15 of 20
15. Question
Ratio of the incomes of Rubha and Usha are 18:19 respectively and their expenditures are in the ratio 33:34 respectively. If Rubha saves Rs.3000 and Usha saves Rs.4000 respectively. Find the sum of the incomes of Rubha and Usha.
Correct
Answer c
Explanation:
Let the incomes of Rubha and Usha are Rs.18x and Rs19x respectively.
According to the question
(18x – 3000)/(19x – 4000) = 33/34
=> 612x – 102000 = 627x – 132000
=> 15x = 30000
=> x = 2000
Sum of the incomes of Rubha and Usha
= > 18x + 19x = 37x
= > 37 * 2000 = Rs.74000
Incorrect
Answer c
Explanation:
Let the incomes of Rubha and Usha are Rs.18x and Rs19x respectively.
According to the question
(18x – 3000)/(19x – 4000) = 33/34
=> 612x – 102000 = 627x – 132000
=> 15x = 30000
=> x = 2000
Sum of the incomes of Rubha and Usha
= > 18x + 19x = 37x
= > 37 * 2000 = Rs.74000
