Given the cost price of the articles = Rs. 450
To get overall 20% gain,
Total Selling Price = (20/100) x 450 = 540
One third of the CP = 1/3 x 450 = Rs. 150
But given 1/3 of articles are sold at 10% loss
S.P of 1/3 of articles = 90% of 150
= 90 x 150/100 = 135
Then, S.P on remaining 2/3 goods must be
= 450 - 135 = 405 ...........(1)
CP on remaining goods
= 2/3 x 450 = 300 ............(2)
Profit = SP - CP = 405 - 300 = 105
Profit % = (105/300) x 100
= 35%.
22020 ÷ 0.011 = 2001818.181 ? 2000000
In 12 h, they are at a right angles, 22 times.
So, in 24 h, they are at right angles, 44 times.
P.W. = | 100 x T.D. | = | 100 x 168 | = 600. |
R x T | 14 x 2 |
∴ Sum = (P.W. + T.D.) = Rs. (600 + 168) = Rs. 768.
Each number is double the preceding one plus 1. So, the next number is (255 x 2) + 1 = 511.
Here, n(5) = {a, e, i,o, u}
and E = Event of selecting the vowel i = {i}
? P(E)= n(E)/n(S) = 1/5
? 90A/100 = 30B/100 = (30/100) x AC/100
? C = 100 x (100/30) x (90/100) = 300
