Question

Ava Made 100 cranes and B made 3/4 of the number of the paper cranes to Ava. Ava gave 9/20 of her cranes to B. Then, B gave 1/4 of her paper to Ava. How many more cranes did B have than Ava in the end?

Answer 1

B have 5 more cranes than Ava.

Explanation:

As per question statement:

Number of cranes with Ava = 100

Number of cranes with B =
`(3)/(4)` of the paper cranes that Ava has

`\therefore` Number of cranes with B =
`(3)/(4)* 100 =75`

Now, let us proceed step by step.

Step 1: Ava gave
`(9)/(20)` of her cranes to B:

i.e.
`(9)/(20) * 100 = 5 * 9 =45` cranes given to B

Now, number of cranes with Ava = 100 - 45 = 55

Number of cranes with B = 75 + 45 = 120

Step 2: B gave
`(1)/(4)` of her paper cranes to Ava:

i.e.
`(1)/(4) * 120 = 30` cranes given to B

Now, number of cranes with Ava = 55 + 30 = 85

Number of cranes left with B = 120 - 30 = 90

So, the answer is:

Number of cranes that B have more than that of Ava = 90 - 85 = 5
