Question

jim has three times as many comic books as Charlie Charlie has two thirds as many books bob. bob has 27 books how many comic books does Jim have.

Answer 1

Find out the how many comic books does Jim have.

To proof

Let us assume that comic books Jim have be u.

Let us assume that comic books Charlie have be v .

Let us assume that comic books bob have be w .

As given

jim has three times as many comic books as Charlie

thus

u = 3v

Charlie has two thirds as many books bob.

Thus

`v = (2w)/(3)`

bob has 27 books .

i.e w = 27

Put this in the equation

`v = (2w)/(3)`

`v = (2* 27)/(3)`

Solving

v = 18

thus

comic books Charlie has be 18 .

Put v = 18 in the u = 3v

u = 3 × 18

= 54

comic books Jim has be 54 .

Hence proved
