Question

In an exhibition Karan got 10 marks more than Bhavna . Isha got 5 marks less than Bhavna. If trio get a a total of 170 , then what is the marks obtained by Isha?

Answer 1

⛦ Given :

• Karan got 10 marks more than Bhavna
• Isha got 5 marks less than Bhavna.
• Total marks obtained by all three is 170.

⛦ To find :

• The marks obtained by Isha.

⛦ Solution :

Let the marks obtained by Bhavna be x

Then marks obtained by Karan is x + 10

And Marks obtained by Isha = x - 5

Now,

A/Q

↠ (x) + (x + 10) + (x - 5) = 170

↠ x + x + x + 10 - 5 = 170

↠ 3x + 5 = 170

↠ 3x = 170 - 5

↠ 3x = 165

↠ x = 165/3

↠ x = 55

-----------------------

Hence,

• Marks obtained by Bhavna = 55
• Marks obtained by Karan = x + 10 = 55 + 10 = 65
• Marks obtained by Isha = x - 5 = 55 - 5 = 50

Therefore,

Final Answer :

Marks obtained by Isha is 50.

Answer 2

Given :

• Karan got 10 marks more than Bhavna
• Isha got 5 marks less than Bhavna.
• Total marks obtained by them is 170.

To find :

• Marks obtained by Isha.

Required Solution :

• Let the marks obtained by Bhavna be x
• Let the marks obtained by Karan is x + 10
• Let the marks obtained by Isha = x - 5

According to the Question,

$\\ \sf➠ (x) + (x + 10) + (x - 5) = 170 \\ \\ \sf \: \: ➠ \: (x + x + x) + 10 - 5 = 170 \: \: \: \: \: \: \\ \\ \sf \: ➠ \: 3x + 5 = 170 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \: ➠ \: 3x = 170 - 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \: ➠ \: 3x = 165 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \: ➠ \: x = \frac{165}{3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \: ➠ \: x = 55 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Therefore,

• The marks obtained by Bhavna = 55
• The marks obtained by Karan = x + 10 ➙ 55 + 10 = 65
• The marks obtained by Isha = x - 5 ➙ 55 - 5 = 50

Hence,

• The marks obtained by Isha is 50.
