- Question
If 1/8 of a pencil is black, 1/2 of the remaining is white and the remaining, 3/2cm is blue. Find the total length of the pencil?
Options- A. 8 cms
- B. 7 cms
- C. 9 cms
- D. 11 cms
- Correct Answer
- 8 cms
ExplanationLet 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: 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.

Then new price of the car

So required percentage =(x/4)/(5x/4) × 100%
= 20%
