Correct Answer: 331/3%
Explanation:
Here, a = 16, b = 12
According to the formula,
Required gain percent = [(a - b)/b] x 100
= [(16 - 12)/12] x 100
= (4/12) x 100
= 331/3% (gain)
Correct Answer: 12
Explanation:
Correct Answer:
Explanation:
(SP of 100 pens) - (CP of 100 pens) = SP of 40 pens
? SP of 60 pens = CP of 100 pens.
Let CP of each pen = ? 1
Then, CP of 60 pens = ? 60
SP of 60 pens = ? 100
Gain = 100 - 60 = ? 40
? Gain % = (40/60) x 100 % = 66.67%
Correct Answer: 21
Explanation:
Cost price of 11 Articles = 10
Cost price of 1 Article = 10/11
and SP of 10 Articles = 11
? SP of 1 Article = 11/10
Now, gain = (11/10) - (10//11)
= (121 - 100)/110 = 21/110
And gain% = [(21/110) / (10/11)] x 100
= (21 x 11)/11 = 21
Correct Answer: 56.26%
Explanation:
Let the number of pens bought = 5 x 4 = 20
Then, CP = (4/5) x 20 = ? 16
and SP = (5/4) x 20 = ? 25
? Gain = 25 - 16 = ? 9
Gain % = (9/16) x 100% = 56.25%
Correct Answer: ? 50
Explanation:
Let CP of the article be ? N,
Then 106% of N - 94% of N = 6
? 12% of N = 6
? N = (6 x 100)/12 = ? 50
Correct Answer: 4% loss
Explanation:
Required loss = (a/10)2%
= (20/10)2% = 4%
Thus, seller gets 4% loss in the deal.
Correct Answer: Rs. 50
Explanation:
? 6% of C.P. + 6% of C.P. = Rs. 6
? 12% of C.P. = Rs. 6
? 12 / 100 x CP = 6
? CP = (100 x 6) / 12 = 50
? C.P. = Rs. 50
Correct Answer: 30%
Explanation:
Let the CP be ? 100 and let MP be ? x above ? 100.
Then, MP = ? (100 + x) and discount =10%
? SP = [(90/100) x (100 + x)] = ? 177
? x = 30
So, cost should be labelled at 30% above CP.
Correct Answer: 12.5% gain
Explanation:
Here, a = 10% and b = 20%
According to the formula,
Required answer= [b ± a/(100 - b)] x 100 %
= (20 - 10)/(100 - 20 ) x 100%
= (10/80) x 100% = 12.5 % gain
+ ve sign show that profit is earned here.
