Correct Answer: 23
Explanation:
Total number of female members = 115
Let the number of males = x
Number of females = y
=> x + y = 115 ......(1)
According to the given data,
x + y(0.50) = 69 ......(2)
From (1) & (2), we get
0.5y = 46
=> y = 46 x 2 = 92
=> x = 115 - 92 = 23
Hence, required number of gentlemen in the family = x = 23.

Correct Answer: 90 min
Explanation:
Let X = Time taken for each of Type B Problems(100 Problems)
And 2X = Time taken for each of Type A problems(50 problems)
Total time period = 3hrs = 3 x 60min = 180 minutes
100X + 50(2X) = 180
100X + 100X = 180
200X = 180 min
X = 180/200
X = 0.90 min
By convertiing into seconds,
X = 0.90 x 60 seconds
X = 54 sec
So, time taken for Part A problems is = 54 x 2 x 50 = 5400 seconds
= 5400/60sec = 90 minutes.
Correct Answer: 1060
Explanation:
From the given data,
80 x 15/100 of 80 + 5 x 80 x 25/100

Correct Answer: 8 cms
Explanation:
Let the total length of the pencil = x cms
From the given data,
'x/8' is black
Remaining part = x - x/8 = 7x/8
1/2 of 7x/8 is white
=> 7x/16 is white (Remaining part is 7x/16)
And given that the remaining part is blue and is 3 1/2 cm = 7/2 = 3.5 cm
That remaining part = 7x/16
Therefore,
7x/16 = 7/2
x = 16/2 = 8
Hence, the total length of the pencil = x = 8 cm.
Correct Answer: 100%
Correct Answer: 20%
Explanation:
Suppose that the original price of the car = Rs. x
Then new price of the car
=> (x) + (x ×25/100) = Rs. 5x/4
To restore the original price, the new price must be decreased by
5x/4 ? x = x/4
So required percentage =(x/4)/(5x/4) × 100%
= 20%
