Solutions

S1. Ans.(d)

Sol. Number of girls = 100

∴ Number of boys = 300 

∴ Number of hostel dwellers = 50 + 100 = 150 

⇒ Required ratio = 150 : 400 

=3∶8=3/8 

S2. Ans.(d)

Sol. Let the incomes of the two persons be 4I and 5I respectively

Let the expenditure of the two persons be 7E and 9E respectively.

∴ 4I - 7E = 50 and 5I - 9E = 50 

⇒ 20I - 35E = 250

20I - 36E = 200 

E = 50 and I = 100 

∴ Monthly incomes of the two persons are Rs.400 and Rs. 500 respectively. 

S3. Ans.(a)

Sol. Let, initially, the number of males and females in the bus be 3x and x respectively. 

At the first stop, suppose m males and f females left the bus. 

∴ At the first stop: Number of the males is 3x - m 

And number of females 

 

∴ f = 4, x = 16 

∴ Total number of passengers in the beginning 

= 4x = 64 

For no other value of f any of the other alternatives holds good.  

S4. Ans.(a)

Sol. Let X’s income be 3k then Y’s income is 4k. Let X’s expenditure be 4g then Y’s expenditure is 5g. 

 

S6. Ans.(c)

Sol. Let x pairs brown socks were ordered 

Let p be the price of a brown pair 

∴ 2p is the price of a black pair 

∴ (2p × 4 + px) + 50% of (2p × 4 + px) 

= 2p × x + 4p 

⇒ x = 16 

∴ Required ratio = 1 : 4 

S7. Ans.(b)

Sol. Let the quotes of A and B be 7X and 4X, respectively. 

After decreasing, quotes of A = 4x - 1 

Then, we are given 

 

⇒ X = 1

Then, decreasing by A = 7X - (4X - 1) 

= 3x + 1 = 3 + 1

= Rs. 4 lakhs 

S8. Ans.(c)

Sol. Student studies for 9 hrs from 11 am to 8 pm on Monday to Friday 

Also, be studies 1/3rd of the time on Sunday i.e. 1/3×9=3h 

Total hours, he studied during the week 

= 5 × 9 + 3 = 45 + 3 = 48h 

Total hours, in a week = 24 × 7 = 168 

∴ Required fraction 

=48/168=2/7 

S9. Ans.(a)

Sol. Ratio of personal shares = 6 : 5 : 4 

Ratio of the amounts = 12 : 15 : 16 

Ratio of men, women and children 

=12/6 ∶15/5 ∶16/4 

= 2 : 3 : 4 

Sum of these ratios = (2 + 3 + 4) = 9 

Number of men =((45 × 2)/9)=10 

Number of women =((49 × 3)/9)=15 

And, the number of children = 45 - (10 + 15) = 20 

Now, dividing Rs. 430 in the ratio = 12 : 15 : 16 

Total amount of men’s share 

= Rs. ((430 × 12)/43) 

= Rs. 120 

Total amount of women’s share 

= Rs. ((430 × 15)/43) 

= Rs. 150 

Total amount of children’s share 

= Rs. [430 - (120 + 150)] 

= Rs. 160 

∴ Each man’s share = Rs. (120/10)=Rs.12 

Each woman’s share = Rs. (150/15)= Rs. 10 

Each child’s share = Rs. (160/20) = Rs. 8 

S10. Ans.(d)

Sol. Ratio of the amount collected from the 1st class and the 2nd class passengers = 3 : 50 

∴ Amount collected from the 2nd class passengers 

=50/53×1325 = Rs. 1250.

S12. Ans.(b)

Sol. According to question, 

5x/(72x + 8)=5/74 

⇒ x = 4 

Managers = 5 × 4 = 20 

S13. Ans.(b)

Sol. Mayank paid 1/2 of the sum paid by other three. 
Let the other three paid Rs. x jointly, then Mayank paid x/2

So, x+x/2=60,000 ⇒ x = 40,000. 

Hence, Mayank paid = Rs. 20,000 

Likewise, Mirza and Little paid Rs. 15,000 and Rs. 12,000 respectively. 

Hence, the amount paid by Jaspal is 
Rs. [60,000 - (20,000 + 15,000 + 12,000)] = Rs. 13,000  

S14. Ans.(d)

Sol. Ratio of number of one rupee, fifty paise, and twenty five paise coins = 2.5 : 3:4 

∴ Ratio of value of coins =2.5×1∶3/2 ∶4/4=5∶3∶2 

Let, amount of Rs 1, 50 paise and 25 paise coins be 5x, 3x and 2x respectively. 

So, 5x + 3x + 2x = 210 (given) ⇒ x = 21 

∴ Value of one rupee coins 

= number of one rupee coins = 21 × 5 = 105
