Options- A. 20%
- B. 24%
- C. 21%
- D. 25%
- Correct Answer
- 20%
ExplanationSuppose 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%

Correct Answer: 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: 1060
Explanation:
From the given data,
80 x 15/100 of 80 + 5 x 80 x 25/100

Explanation:

Correct Answer: 23
Explanation:
Total number of female members = 115
Let the number of males = x
Number of females = y

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.
