उत्तर

Given that fixed increment in the salary of a man

= Rs. 320 each month

Initial salary = Rs. 5200 which makes an A.P

whose first term (a) = Rs. 5200 and common difference (d) = Rs. 320

Salary for the tenth month 

a10 = a + (n – 1)d

= 5200 + (10 – 1) × 320

= 5200 + 2880

= Rs. 8080

Hence, the required amount is Rs. 8080
