Initial annual salary of X  = Rs.300 × 12 = Rs.3600
Annual increment of X = Rs 30 × 12 = Rs.360
 
Total salary of X for 10 years will be obtained using arithmetic progression, with initial value Rs. 3600 and
difference Rs.360 for 10 years as given below
 
Total salary of X = (10/2) [ 2×3600 + 9×360 ] = Rs. 52200
 
Initial half-reary salary of Y =Rs.200×6 = Rs. 1200
Half-yearly increment of Y = Rs.15×6 = Rs.90
 
Total salary of Y for 10 years or 20 half-yearly period  will be obtained using arithmetic progression,
with initial value Rs. 1200 and difference Rs.90 for 20 half-year period as given below
 
Total salary of Y = (20/2)[ 2×1200 + 19×90 ] = Rs. 41100
 
Total salary paid to X and Y = Rs. 52200 + Rs. 41100 = Rs. 93300
