Question : 1
My son adores chocolates. He likes biscuits. But he hates apples. I told him that he can buy as many chocolates he wishes. But then he must have biscuits twice the number of chocolates and apples more than biscuits and chocolates together. Each chocolate costs Re. 1. The cost of apple is twice of chocolate and four biscuits are worth of one apple. Then which of the following can be the amount that I spent on that evening on my son?
a) Rs 33
b) Rs 8
c) Rs 34
d) None of these
Answer »Answer: (c)
If number of chocolates is NC then those of biscuits
$N_B = 2N_C$
and number of apples i.e $N_A > 3N_C$
also, total amount spent
= $2N_A + N_C + 1/4 (2N_B) = 2N_A + 2N_C$
(note that amount of money spent is even number)
option (b) 33 = 8 + 24 + 1
but 2$N_A$ ≠ 25
option (c) is not possible
So, option (a) 34 = 8+ 24 + 2
$↙{even}2N_A, [N_A > 3N_C also]↙{satisfied}$
So, option (c) is correct
Directions:
Study the following information and answer questions that follow :
Bankatlal works x hours a day and rests y hours a day. This pattern continues for 1 week, with an exactly opposite pattern next week, and so on for four weeks. Every fifth week he has a different pattern. When he works longer than he rests, his wage per hour is twice what he earns per hour when he rests longer than he works. The following are his daily working hours for the weeks numbered 1 to 13
1st week | 5th week | 9th week | 13th week | |
Rest | 2 | 3 | 4 | - |
Work | 5 | 7 | 6 | 8 |
A week consist of six days and a month consists of 4 weeks
Question : 2
Referring to the data given in previous question, Bankatlal's average monthly salary at the end of the first four months will be
a) 2040
b) 1830
c) 1760
d) 1680
Answer »Answer: (b)
Salary for 5th and 7th week = 2 × 7 × 20 × 6 = Rs 1680
Salary for 6th and 8th week = 2 × 3 × 10 × 6 = Rs 360
Salary for 2nd month = 1680 + 360 = Rs 2040
Similarly salary for 3rd month
= 2(6 × 20 × 6) + 2 ( 4 × 10 × 6)
= 1440 + 480 = Rs 1920
Salary for 4th month = 2(8 × 20 × 6) + 2 (0) = Rs 1920
Salary at the end of 4 months
= 1440 + 2040 + 1920 + 1920
= Rs 7320
∴ Average monthly salary = ${7320}/4$ = Rs 1830
Question : 3
The new manager Khushaldas stipulated that Rs 5 be deducted for every hour of rest and Rs 25 be paid per hour starting 9th week, then what will be the change in Bankatlal's salary for the 3rd month? (Hourly deductions and salaries are constant for all weeks starting 9th week)
a) 480
b) 240
c) 540
d) 0
Answer »Answer: (a)
Under new scheme salary for 9th and 11th week
= 2 (25 × 6 – 5 × 4 ) × 6 = Rs 1560
Now salary for 10th and 12th week = 2( 25 × 4 – 5 × 6 ) × 6
= Rs 840
Total salary for 3rd month = 1560 + 840 = Rs 2400
Under previous scheme total salary for 3rd month
= Rs 1920
Difference = 2400 – 1920 = Rs 480
