Total actual cost = Rs. (84 ´ 240 + 3200)
= Rs. (20160 + 3200)
= Rs. 23360
S.P. of each shirt = 420 ´ 85/100 = Rs. 357
S.P of 84 shirts = 84 ´ 357
= Rs. 84 shirts = 84 ´ 357 = Rs. 29988
Profit = 29988 – 23360 = Rs. 6628
2.(1)
Let the cost price of the article be Rs. x
According to the equation,
1516 – x = x – 1112= 2x = 1516 + 1112= 2628
x = 2628/2 = Rs. 1314
3.(1)
Let the CP of the article be Rs. x
According to the question.
1754 – x = x – 1492=
2x = 1754 + 1492 = 3246
= x = 3246/2 = Rs. 1623
4.(3)
First S.P. = 90/100 × 800 = Rs. 720
If the market price be Rs. x, then
= x × 80/100 = Rs.720
= x = 720 × 100/100 = Rs. 900
∴ Required loss per cent
= 900 – 720/900 × 100 = 20%
5.(1)
Let Vinod have x pencils.
∴ 2.5 × x – 1.75 × x = 110 + 55
= 0.75 × x = 165
= x= 165/0.75 = 220
6.(4)
Cost price of 30 kg of wheat = 30 × 45
= Rs. 1350
Total SP for an overall profit of
= 25% = 1350 × 125/100
= Rs. 1687.5
SP of 12 kg (30 × 40/100) of wheat
= 12 × 50 = Rs. 600
Expected SP of 18 kg of remaining wheat
= 1687.5 – 600 = Rs. 1087.5
Required selling price per kg
= 1087.5/18 = Rs. 60
7.(2)
(Tricky Approach)
Gain per cent
(348000 – 250000)/250000 × 100
= 39.2%
8.(3)
Total CP
= Rs. (12000 + 10000)
=Rs. 22000
Total S.P.
= Rs. (12000 × 108/100 + 10000 × 88/100)
= Rs. (12960 + 8800)
= Rs. 21760
∴ Loss = Rs. (22000 – 21760)
= Rs. 240
9.(4)
Commission earned in one day
= Rs. (10 × 45 × 4)/100 + Rs. (80 × 20 × 6)/100
=Rs. 114
∴ Commission earned in two weeks
= Rs. 114 × 14 = Rs. 1596
10.(2)
C.P. of wristwatch= 100/100 – loss % × S.P.
= Rs. (100/75 × 2400)= 3200 Rs.
∴ Required S.P. of wristwatch= (125/100 × 3200)
= Rs. 4000
