There is a doll that can make 2 musical sounds. it makes 2 musical sounds after being defective. what is the probability that the same musical sound would be produced 5 times consecutively?

Solution

There are two sounds A and B,
In first chance the doll can produce any of the two sounds so probability = 1
After that for making the same sound to be produced, probability = 1/2
similarly for the other chances thus answer will be 1*(1/2)*(1/2)*(1/2)*(1/2) = 1/16

(#M40001052) TCS QUESTION Keep an EYE

The age of two people is in the ratio 6:6. if the sum of their ages is 44.after how many years would the ratio be 8:7?

Solution

The ratio given is 6:6 means both are same in age it means it will be impossible to make their age ratio 8:7
now if we consider the suggestion given by RISHABH, then
present ratio = 6:5 = 24:20 sum of ages = 44 so ages are 24 and 20
let after x years ratio will be 8:7 , so (24+x)/(20+x) = 8/7
on solving the equation we get x = 8
