A, B and C can do a piece of work in 20, 30 and 60 days respectively. In how many days A do the work if he is assisted by B and C on every third day? | [
"15 days",
"19 days",
"18 days",
"17 days"
] | A | A's 2 day's work = (1/20 * 2) = 1/10

Work done in 3 days = (1/10 + 1/10) = 1/5
Now, 1/5 work is done in 3 days.
Whole work will be done in (3 * 5) = 15 days.

In a certain year, the population of a certain town was 9000. If in the next year the population of males increases by 2% and that of the females by 8% and the total population increases to 9600, then what was the ratio of population of males and females in that given year? | [
"4 : 5",
"None of these",
"2 : 7",
"Data inadequate"
] | C | Let the population of males = x; then the population of females = 9000 – x
Now, 2% of x + 8% of (9000 – x)
= (9600 – 9000 ) = 600
or 0.02x + 720 – 0.08x = 600

"6,13",

Distance from starting point=Hypotenuse of a right triangle with sides x & (x+7)
So 13^2=x^2+(x+7)^2
x^2+7x-60=0 or (x+12)(x-5)=0, so x=5
Distance towards west=x+7=5+7=12 km.
