Question

When their reports cards came back, Pete, Chris, and Dina realized that they shared an amount of A’s in the ratio 4:2:5. If Pete got 14 more A’s than Chris, how many A’s did Dina get?

Answer 1

Answer:

35 A's

Step-by-step explanation:

Let  the ratio be x

∴ the ratio would be 4x : 2x : 5x

A.T.Q

4x-2x=14

x=7

hence, Dina got 5*7 A's , that is 35

Answer 2

Answer:

35

Step-by-step explanation:

Easy peesy.

Let P stands for Pete, C for Chris, D for Dina

If you are not a big fan of Algebra always start assuming the values in ratios related questions.

I am assuming P has 4 A's

which means C should have 2 A's

and D should have 5 A's

Given : P has 14 more A's than C

But for my assumed value P only has (4-2 = 2) 2 extra A's than C

To make it 14 I have to multiply it by 7.

Now P will have 4*7 = 28

        C will have 2*7 = 14

        D will have 5*7 = 35

Hope this helps.
