Correct Answer: Rs. 5220
Explanation:
Remaining % of amount with Rohan
= 100 - (24 + 34 + 17 + 19)
= 100 - 94
= 6%
=> 6% = 540
=> 100% = ?
540 x 100/6 = Rs. 9000
Now, Money spent on insurance and food is
= 34 + 24 = 58% of 9000
= 58 x 9000/100
= 58 x 90
= Rs. 5220
Correct Answer: 200
Explanation:
5% of 4000
= 5 x 4000/100
= 5 x 40
= 200
Hence, 5% of 4000 = 200.
Correct Answer: 24%
Explanation:
Let the cost price of each mango be Rs. 1
So 50 mangoes costs = Rs. 50
20% Profit on Selling Price of 10 mangoes = Rs. 12
30% Profit on Selling Price of 20 mangoes = Rs. 26
Total = Rs. 38
Loss = 50 - 38 = 12
Loss% = (12/50) x 100 = 24%.
Correct Answer: 1060
Explanation:
Given total number of students = 80
Total teachers = 5
Number of coupons each student got = 15 x 80/100 = 12
Number of coupons each teacher got = 25 x 80/100 = 20
Therefore, total number of shopping coupons = 80 x 12 + 5 x 20 = 960 + 100 = 1060.
Correct Answer: 20%
Explanation:
Percentage of students passed in English = 60%
Percentage of students passed in Hindi = 45%
Percentage of students passed in both subjects = 25%
ATQ,
Percentage of students passed in only English = 60 - 25 = 35%
Percentage of students passed in only Hindi = 45 - 25 = 20%
Therefore, Percentage of students failed = 100 - (35 + 25 + 20)
= 100 - 80 = 20%.
Correct Answer: Rs.300
Correct Answer: 11 1/9%
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).
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: 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%
