Capgemini Company Numerical Ability Percentage

A rainy day occurs once in every 10 days. Half of the rainy days produce rainbows. What percent of all the days do not produce rainbow?
A)95% B)10% C)50% D)5%

Read Solution (Total 2)

Assume total days to be 100.
Rainy day occurs in every 10 days, so 100/10 = 10
10 days out of 100 are rainy days.
Half means 5 out of 10 days produce rainbow.
Days when no rainbow : 100-5 = 95
So, required answer is : 95*100/100 = 95%

A robot moves on a graph sheet with xy axes. The robot is moved by feeding it with a sequence of instructions. The different instructions that can be used in moving it, and their meanings are: Instruction Meaning GOTO(x,y) move to pt with coord (x,y) no matter where you are currently WALKX (P) move parallel to x axis through a distance of p, in the +ve direction if p is +ve and in –ve if p is –ve WALKY(P) move parallel to y axis through a distance of p, in the +ve direction if p is +ve and in –ve if p is –ve
Question: The robot reaches point (5,6) when a sequence of 3 instr. is executed, the first of which is GOTO(x,y) , WALKY(2), WALKY(4). What are the values of x and y?
A) 2,4 B) 0,0 C) 3,2 D) 2,3 If 5 spiders can catch five flies in five minutes. How many flies can hundred spiders catch in 100 minutes?
A)100 B)1000 C)500 D)2000
