80 is what percent of 64?

80 is what percent of 64?

A. 85%
B. 120%
C. 75%
D. 125%
E. None of these
Let x percent of 64 be 80.
64 * x/100 = 80 => x = (80 * 100)/64 => x = 125
80 is 125% of 64.

A. 37
B. 38
C. 39
D. 40
Explanation:
Perimeter = 2×(36+21) m = 114 m
Number of flag staffs = (114/3) = 38

A sells a bicycle to B at a profit of 20%. B sells it to C at a profit of 25%. If C pays Rs. 225 for it, the cost price of the bicycle for A is:________?

A sells a bicycle to B at a profit of 20%. B sells it to C at a profit of 25%. If C pays Rs. 225 for it, the cost price of the bicycle for A is:________?

A. Rs. 110
B. Rs. 120
C. Rs. 125
D. Rs. 150
Explanation:
125% of 120% of A = 225
125/100 * 120/100 * A = 225
A = 225 * 2/3 = 150.

A fruit vendor purchased 20 dozens of bananas at Rs. 15 per dozen. But one-fourth of the bananas were rotten and had to be thrown away. He sold two-third of the remaining bananas at Rs. 22.50 per dozen. At what price per dozen should he sell the remaining bananas to make neither a profit nor a loss?

A fruit vendor purchased 20 dozens of bananas at Rs. 15 per dozen. But one-fourth of the bananas were rotten and had to be thrown away. He sold two-third of the remaining bananas at Rs. 22.50 per dozen. At what price per dozen should he sell the remaining bananas to make neither a profit nor a loss?

A. Rs. 20
B. Rs. 15
C. Rs. 22.50
D. Rs. 7.50
E. None of these
Explanation:
CP of 20 dozen of bananas = 15 * 20 = Rs. 300
Number of bananas which are rotten = 1/4 * 20 = 5 dozen.
SP of two-third of remaining bananas = (2/3 * 15) * 22.5 = Rs. 225
SP of remaining 5 dozens of bananas to make no profit and no loss =(300 – 225) = Rs. 75.
SP of 1 dozen bananas = 75/5 = Rs. 15.
