Answer 1

Answer:

hey!

Step-by-step explanation:

question:_ Dipin's score is 15% more than that of Rafi. Rafi's score is

10% less than that of Chandar. If the difference between the

scores of Dipin and Chandar is 14, what is the score of Rafi?

ATQ,

Let us assume that Chandar's score = 100

Given that, Rafi's score is 10% less than that of Chandar.

Rafi's score = 90

but,

Dipin's score is 15% more than that of Rafi.

∴

Dipin's score = 115% of 90

= 115/100 x 90

= 103.5

Now, the difference between the scores of Dipin and Chandar = 103.5 - 100

= 3.5.

If the difference between the scores of Dipin and Chandar is 3.5 then Rafi's score = 90

If the difference is 14, then Rafi's score = 90/3.5 x 14

= 360

Hence, the required answer is 360.
