1 If each black wallet, each red wallet, each blue wallet and each white wallet sold by shopkeeper A was Rs. 80, Rs. 60, Rs. 50 and Rs. 40 respectively then what was the amount generated by shopkeeper A after selling the wallets?
A Rs. 30500
B Rs. 32700
C Rs. 33200
D Rs. 31600
E Rs. 38700
Correct Option: B
Following the common explanation, we get
The amount generated by shopkeeper A after selling the wallets = 120 × 80 + 145 × 60 + 140 × 50 + 185 × 40 = Rs. 32700
Hence, option B is correct.
Common Explanation:
Total blue wallet sold by all four = 2705 – (700 + 585 + 660) = 760
Blue wallet sold by B = 760 – (140 + 330 + 70) = 220
Total wallet sold by B = 225 + 165 + 220 + 45 = 655
Total wallet sold by D = 2705 – (590 + 655 + 850) = 610
Black wallet sold by D = 610 – (195 + 70 + 170) = 175
Black wallet sold by C = 700 – (120 + 225 + 175) = 180
White wallet sold by C = 850 – (180 + 80 + 330) = 260
White wallet sold by A = 660 – (170 + 260 + 45) = 185
Red wallet sold by A = 590 – (120 + 140 + 185) = 145
2 What is the total wallet sold by D?
A 610
B 520
C 680
D 570
E 540
Correct Option: A
Following the common explanation, we get
Wallet sold by D = 2705 – (590 + 655 + 850) = 610
Hence, option A is correct.
Common Explanation:
Total blue wallet sold by all four = 2705 – (700 + 585 + 660) = 760
Blue wallet sold by B = 760 – (140 + 330 + 70) = 220
Total wallet sold by B = 225 + 165 + 220 + 45 = 655
Total wallet sold by D = 2705 – (590 + 655 + 850) = 610
Black wallet sold by D = 610 – (195 + 70 + 170) = 175
Black wallet sold by C = 700 – (120 + 225 + 175) = 180
White wallet sold by C = 850 – (180 + 80 + 330) = 260
White wallet sold by A = 660 – (170 + 260 + 45) = 185
Red wallet sold by A = 590 – (120 + 140 + 185) = 145
3 What is the ratio of white wallet sold by A to red wallet sold by C?
A 22 : 7
B 37 : 16
C 32 : 21
D 19 : 11
E 11 : 8
Correct Option: B
Following the common explanation, we get
Required ratio = 185 : 80 = 37 : 16
Hence, option B is correct.
Common Explanation:
Total blue wallet sold by all four = 2705 – (700 + 585 + 660) = 760
Blue wallet sold by B = 760 – (140 + 330 + 70) = 220
Total wallet sold by B = 225 + 165 + 220 + 45 = 655
Total wallet sold by D = 2705 – (590 + 655 + 850) = 610
Black wallet sold by D = 610 – (195 + 70 + 170) = 175
Black wallet sold by C = 700 – (120 + 225 + 175) = 180
White wallet sold by C = 850 – (180 + 80 + 330) = 260
White wallet sold by A = 660 – (170 + 260 + 45) = 185
Red wallet sold by A = 590 – (120 + 140 + 185) = 145
4 C gives discount on some wallet. 20% of black wallet, 30% of red wallet, 10% of blue wallet and 15% of white wallet sold at discount. Find total wallet sold at discount by C.
A 152
B 128
C 132
D 108
E 116
Correct Option: C
Following the common explanation, we get
Total wallet sold at discount by C = 20% of 180 + 30% of 80 + 10% of 330 + 15% of 260 = 36 + 24 + 33 + 39 = 132
Hence, option C is correct.
Common Explanation:
Total blue wallet sold by all four = 2705 – (700 + 585 + 660) = 760
Blue wallet sold by B = 760 – (140 + 330 + 70) = 220
Total wallet sold by B = 225 + 165 + 220 + 45 = 655
Total wallet sold by D = 2705 – (590 + 655 + 850) = 610
Black wallet sold by D = 610 – (195 + 70 + 170) = 175
Black wallet sold by C = 700 – (120 + 225 + 175) = 180
White wallet sold by C = 850 – (180 + 80 + 330) = 260
White wallet sold by A = 660 – (170 + 260 + 45) = 185
Red wallet sold by A = 590 – (120 + 140 + 185) = 145
