Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 197.5
Let the cost of a pen and a pencil be X and Y
The cost of 32 pens and 12 pencils is ₹790
According to the question
⇒ 32 X + 12 Y = 790
⇒ 4(8 X + 3 Y) = 790
⇒ 8X + 3 Y = 790/4 = 197.5
Hence, the cost of 8 pens and 3 pencils together is Rs. 197.5
