Correct Answer: 20%
Explanation:
Let the S.P. be Rs. P Then, C.P. paid by subhash = Rs. (9 x P)/10 S.P. received by subhash = (108% of Rs. P) = Rs. (27 x P) / 25 ∴ Gain = Rs.(27 x P) / 25 - (9 x P) / 10 = Rs. (9 x P) / 50 Hence, Gain% = (9P / 50) x (10P / 9) x 100 % = 20%
Correct Answer: 14.66%
Explanation:
There is no need to use the no of goats i.e (34,398). let initially thete be 1000 goats then
1000 -----> 1400 -----> 980 -----> 1274 ----->1146.6
Thus the % increase = (1146.6-1000)/100 x 100= 14.66%
Correct Answer: 38
Explanation:
Let no. of boys be 'B' and no. of girls be 'G'
Here from given data,
B + G = 1650 .....(1)
B - G = 400 .....(2)
From (1) & (2), we get
2B = 2050
=> B = 1025
=> G = 1650 - 1025 = 625
Hence, the % of girls = 625 x 100/1650
=> 38% (approx).
