(a)7/16 (b)7/32 (c)7/48 (d)7/64

Solution

let p = k/2, q = k/4, r = k/8, on putting these values in 2nd equation, we get
1/2(k/2) + 1/4(k/4) + 1/6(k/8) = 24/7
1/k + 1/k + 4/3k = 24/7
10/3k = 24/7
k = 35/36, on putting k = 35/36, r = (35/36)/8 = 35/288

(#M40001333) CTS QUESTION dontknw Keep an EYE

A survey of a village showed that 1 / 10 of the total population speak neither Hindi nor English. 1 / 5 of them cannot speak English and 3 / 7 of them cannot speak Hindi. What percentages of people know only one language?
A) 42.86 %
B) 40 %
C) 35 %
D) None of these

Solution

persons who can speak English = 1 - (1/5) = 4/5
persons who can speak Hindi = 1 - (3/7) = 4/7
persons who can speak any or both = 1 - 1/10 = 9/10
so total persons speak both = 4/5 + 4/7 - 9/10 = 33/70
persons speak any = 1 - 33/70 - 1/10 = 3/7
% = 300/7 Answer is A

(#M40001331) TCS QUESTION hare&tortoise Keep an EYE

A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has coverd 1/4 of its distance and that too leisurely. The hare and tortoise meet when the hare has covered only 1/8 of the distance.By what factor should the hare increse its speed so as to tie the race?

Solution

Total circumfrance = pie*diameter
tortoise has covered = 25pie
remaining distance = 75 pie
1/8th of total distance = 12.5 pie
let the velocity of tortoise = u and that of hare =v
on time comparison we get
62.5 pie/u = 12.5 pie/v
5v=u so v=u/5

now for remaining journey time taken by tortoise = 12.5 pie/u
so velocity of hare to make a tie = 7*12.5 pie u / 12.5 pie
=7u
so 7u/u/5 = 35 times answer
