In a certain country ½ of 5 = 3. If the same proportion holds, what is the value of 1/3 of 10 ?

4

5/2 = 3 and 10/3 = x

(10/3)/(5/2) = 20/15 = 4/3

So x/3 = 4/3

x=4

Anmol had a bag containing colorful marbles. The colors are red, green and blue. The total number of marbles he had in his bag is 60. There are 4 times as many red marbles as green marbles. 6 more blue marbles than green marbles. How many marbles of each color did Anmol have?

Lets take R as red, G as green and B as blue.

R + G + B = 60

As there are 4 times red marbles than green marbles, then

R = 4G

There are 6 more blue marbles than green marbles, so

B = G + 6

Therefore,

R + G + B = 60

4G + G + G + 6 = 60

6G + 6 = 60

6G = 60 – 6

6G = 54

G = 54/6 = 9

R = 4G = 4 x 9 = 36

B = G + 6 = 9 + 6 =15

Finally there are 9 green marbles, 36 red marbles and 15 blue marbles
