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%
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:

Explanation:
We know that 40% =
40% of 265 + 35% of 180 = 50% ?
x 265 + 35% of 180 = 50% ?
We know that (35% of 180 = 180% of 35) & 180% =
x 265 + x 35 = 50% ?
106 + 63 = 50% ?
?= 2 x 169 = 338.
Correct Answer: 13500
Explanation:
Given in municipality election 54% votes have won by 1080
Let the total number of votes be x.
8x = 108000
x = 13,500
Therefore, total number of votes = 13,500.
Correct Answer: 430
Explanation:
Let the total number of valid votes be 'V'.
70% of V = 70/100 x V = 7V/10
Number of votes secured by the other candidate = V - 7V/100 = 3V/10
Given, 7V/10 - 3V/10 = 172 => 4V/10 = 172
=> 4V = 1720 => V = 430.
