For the following questions answer them individually

Question 1

If x, y, z are three positive numbers such that (A - x): (A - y): (A - z) = 1: 7: 4 and 2A = x+y+z, then x:y:z=

Question 2

If x â‰ yÂ â‰ z â‰ 0Â , $$a^x = b^y = c^z$$ and $$\frac{a}{b} = \frac{b}{c}$$, then $$\frac{y - x}{z - y}$$ =

Question 3

Two different discounts x% and y% are allowed on two items having same cost price and marked price. If $$P_1$$% and $$P_2$$% are respectively the profits on them, x - y =20 and $$P_2 - P_1$$ = 32, then the ratio of their cost price to their marked price is

Question 5

Four students A, B, C and D are running around a circular playground in a college and they take 1. 5 min, 25min, 35min and 20min respectively to complete one round. If a prize money of Rs. K is divided in the ratio of their speeds, then the student who receives_maximum share is

Question 6

The ratio among the following that will have maximum change in its value when 10 is added to both the antecedent and consequent of that ratio, is

Question 7

Distinct number of men, women and children have visited a park in a particular day. The number ofwomen visitors is 7 and the number of children who visited the park is maximum among all the visitors. If the ratio between the number of men and women is the same as the ratio between the number of women and children, then the total number of visitors to the park is

Question 8

If a person covers the same distance by walking, by cycling and by running with speeds in the ratio 1: 9: 3 respectively, then the ratio of the ratios of their times and speeds of the three modes of travel is

Question 9

If the sum of the ratios equivalent to $$16\frac{2}{3}$$%, $$33\frac{1}{3}$$%, 5% and 25% is x% of 15, then x =

Question 10

A student is asked to multiply a number K by 5. But he multiplies K by $$\frac{1}{5}$$ and gets x% error. Next time he multiplies K by $$\frac{1}{25}$$ and gets y% error. Then the percentage increase of y over x isÂ
