Ratio of the ages of Mahesh and Nilesh is 5:x. Mahesh is 18 years younger to Ramesh. After nine years Ramesh will be 47 years old. If the difference between the ages of Mahesh and Nilesh is same as the age of Ramesh, what is the value of x? | [
"14.5",
"14.5",
"14.9",
"14.2"
] | A | Let the present ages of Mahesh, Nilesh and Ramesh be M, N and R respectively.
M/N = 5/x --- (1)
M = R - 18 --- (2)
R + 9 = 47 --- (3)
M - N = R --- (4)
(3) => R = 47 - 9 = 38 years
(2) => M = 38 - 18 = 20 years
(1) => 20/N = 5/x => N = 4x
(4) => 4x - 20 = 38
=> 4x = 58 => x = 14.5

A fruit vendor purchased 20 dozens of apples at $15 per dozen. But one-fourth of the apples were rotten and had to be thrown away. He sold two-third of the remaining apples at a$22.50 per dozen. At what price per dozen should he sell the remaining apples to make neither a profit nor a loss? | [
"$15",
"$18",
"$20",
"$14"
] | A | C
$15
CP of 20 dozen of apples = 15 * 20 = $300
Number of apples which are rotten = 1/4 * 20 = 5 dozen.
SP of two-third of remaining apples = (2/3 * 15) * 22.5 = $225
SP of remaining 5 dozens of apples to make no profit and no loss =(300 - 225) = $75.
SP of 1 dozen apples = 75/5 = $15. | AquaRat_train |
In a 1000 m race, A beats B by 50 m and B beats C by 20 m. In the same race, by how many meters does A beat C? | [
"E)132mj",
"C)822m",
"D)929m",
"A)69m"
] | D | By the time A covers 1000 m, B covers (1000 - 50) = 950 m.
By the time B covers 1000 m, C covers (1000 - 20) = 980 m.
So, the ratio of speeds of A and C =
1000/950 * 1000/980 = 1000/931 So, by the time A covers 1000 m, C covers 931 m.
So in 1000 m race A beats C by 1000 - 931 = 69 m.
