Let p% of 352 is 85
Percentage(%) is generally calculated in the total of 100.

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: 24,000
Explanation:
Let K = Kalyan's monthly salary
N = Nandu's monthly salary
S = Sarnesh's monthly salary.
Then from given data,
12% of K = 16% of N
S = N/2 => N = 2S
K = 16/12 x N = 16/12 x 2S
= 16/6 x 1.08/12 = 16/6 x 0.09 = 0.24 lacs = 24,000
Correct Answer: 126%
Explanation:
Suppose total earnings = Rs. 10000
10% saving = 10000 x (10/100) = Rs. 1000
This year 5% more income than prev year = Rs. 10500
12% saving = 10500 x (12/100) = Rs. 1260
Percentage of amount saved = (1260/1000) x 100 = 126%
