$\huge\bigstar\bf\: Answer$

(c) 325 rs

Step-by-step explanation:

Avg income of Ram and Shyam = 300

→ x/2 = 300

→ x = 300 × 2 = 600

Therefore the sum of income of Ram and Shyam

= 600rs

Avg income of Manu and Sonu = 350

→ y/2 = 350

→ y = 350 × 2 = 700

Therefore the sum of income of Manu and Sonu

= 700 rs

The avg . income of Ram, Shyam ,Manu ,and Sonu = 600 + 700 /4 = 1300/4 = 325 rs
