3 buffaloes eat as much as 4 cows or 2 oxen. At a farm there are 15 buffaloes, 8 oxen and 24 cows. The fodder for these cattle is available for 24days. If 8 more cows & 9 more buffaloes are brought in, how long will the fodder last? | [
"10",
"29",
"18",

] | A | A. To make the problem less confusing, I picked a number between 0 and 1 such as q = 1/4 and calculate:
q = 1/4
q^-1 = 4
q^2 = 1/16
q^(1/2) = 1/2
q^3 = 1/8.
From this, rearrange the number and the median is 1/4, which is q. Answer A | AquaRat_train |

A train passes a platform in 36 seconds. The same train passes a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, The length of the platform is | [
"220",
"240",
"230",
"250"
] | B | Speed of the train = 54 km/hr = (54×10)/36 m/s = 15 m/s
Length of the train = speed × time taken to cross the man = 15×20 = 300 m
Let the length of the platform = L
Time taken to cross the platform = (300+L)/15
=> (300+L)/15 = 36
=> 300+L = 15×36 = 540
=> L = 540-300 = 240 meter

Two pens and three pencils cost 86. Four pens and a pencil cost 112. What is the difference between the cost of a pen and that of a pencil? | [
"Cannot be determined",
"13",
"25",
"19"
] | B | Let the cost of a pen and a pencil be ‘x’ and ‘y’ respectively. We have to find (x – y).
From the question,
2x + 3y = 86 ..... (i)
4x + y = 112 ......(ii)
Subtracting (i) from (ii), we get
2x – 2y = 26 or, x – y = 13

"(100 × m/n)%",

z is m% of y MEANS z= (m/100 )* y------------------------eq2
Find equation of xz
substitute value of y from 2nd equation into Ist equation
so x= (n/100)*(100z/m)
so x= (n/m)z
or x= (100n/m)z/100
so answer E is 100n/m %.E | AquaRat_train |

In a camp, there is a meal for 120 men or 200 children. If 150 children have taken the meal, how many men will be catered to with remaining meal? | [
"10",
"30",

Meal for 200 children = Meal for 120 men
Meal for 1 child = Meal for 120/200 men
Meal for 150 children = Meal for (120×150)/200 men=Meal for 90 men
Total mean available = Meal for 120 men
Renaming meal = Meal for 120 men - Meal for 90 men = Meal for 30 men . Answer : Option B | AquaRat_train |
