Correct Answer: 23/50
Explanation:
Given
Correct Answer: 22
Explanation:
63.5% of 8924.2 +? % of 5324.4 = 6827.5862
=> 63.5% of 8925 + ? % of 5325 = 6830
=> 6830 ~= 5320 + ?(5325)/100
=> ? ~= 22
Correct Answer: Rs. 87400
Explanation:
Let the total amount he had with = Rs. p
From the given data,
p - 38460 - 24468 = 28p/100
p - 28p/100 = 24468 + 38460
72p/100 = 62928
72p = 62928 x 100
p = 62928 x 100/72
p = 87400
Hence, the total amount he had = p = Rs. 87400.
Correct Answer: 209
Explanation:
Given 21% of 500 + 31% of 1100 - 30% of 790 = ?
? = 21 x 5 + 31 x 11 - 3 x 79
? = 105 + 341 - 237
? = 446 - 237
? = 209.
Correct Answer: 300
Explanation:
In that 35% are Hindu, 30% are Sikh, 15% are Muslims
=> 35 + 30 + 15 = 80%
Remaining Boys = 100% - 80% = 20% of 1500
=> 20 x 1500/100 = 300 boys are Christians.
Correct Answer: 29.68
Correct Answer: 85
Correct Answer: 250
Correct Answer: 10
Correct Answer: None of the statements is required
Explanation:
From the given data,
(60 - 45)% = 12.5 + 4
15% = 16.5
=> 100% = ?
100% = 16.5 x 100/15 = 110
Hence, P = 45% of 110 = 45x110/100 = 49.5
Q = 50% of 110 = 55
R = 60% of 110 = 60 x 110/100 = 66
M = 12.5 + 49.5 = 62 or 66 - 4 = 62
Hence, no statement is required to answer.
