Q2. Monthly salary of Dex is 1/4 th of his father’s monthly salary. Dex’s sister’s monthly salary is 2/5th of their father’s monthly salary. Dex’s sister pays Rs 12,800, which is 1/4th of her monthly salary as study loan. Savings and expenses made out of the monthly salary by Dex are in the respective ratio of 3 : 5. How much does Dex save each month?
(a) Rs 12,000
(b) Rs 10,600
(c) Rs 10,400
(d) Rs 12,600
(e) Rs 12,400

S2. Ans.(a)
Sol.
Let his father’s monthly salary = Rs. 20x
∴ Dex’s monthly salary = 5x
And his sister’s monthly salary = 8x
But 1/4  × 8x = 12,800
⇒ x = 6,400
∴ Dex’s salary (monthly) = 32,000
∴ Monthly savings made by Mr. Dex
=3/8×32,000
=12,000

Q3. Poorvi’s age 8 years ago is equal to the sum of present ages of her son and her daughter. 5 years hence, the ratio between her son’s age and her daughter’s age will be 7 : 6 respectively. Poorvi’s husband is 7 years elder than her. Her husband’s present age is thrice the present age of his son. What is their daughter’s present age?
(a) 10 years
(b) 14 years
(c) 12 years
(d) 15 years
(e) 9 years

S3. Ans.(a)
Sol.
Let 5 years hence, age of son and daughter be 7x and 6x years respectively.
∴ Present age of son = (7x – 5) years
Present age of daughter = (6x – 5) years
∴ Present age of mother = (13x – 10 + 8)
= (13x – 2)
∴ Poorvi’s husband’s age = 13x – 2 + 7
= (13x + 5)
ATQ,
13x + 5 = 3 (7x – 5)
⇒ 13x + 5 = 21x – 15
⇒ x = 2.5
∴ Daughter’s present age = 6 × 2.5 – 5 = 10 years

Q4. One-third of the contents of container evaporated on the first day and three fourths of the remaining evaporated on the second day. What part of the contents of the container is left at the end of the second day?

(a) 61 : 29
(b) 61 : 30
(c) 5 : 4
(d) 29 : 61
(e) 4 : 5

Q6. Mr. Pandit owned 950 Gold coins all of which he distributed amongst his three daughters Lalita, Amita and Neeta. Lalita gave 25 Gold coins to her husband, Amita donated 15 Gold coins and Neeta made jewellery out of 30 Gold coins. The new respective ratio of the coins left with them was 20 : 73 : 83.

(a) 415
(b) 380
(c) 400
(d) 350
(e) 360

S6. Ans.(b)
Sol.
Let left coins with them be 20x, 73x and 83x respectively
∴ (20x + 25) + (73x + 15) + (83x + 30) = 950
⇒ x = 5
∴ Amita’s part = 73 × 5 + 15 = 380
