Answer 1

Step-by-step explanation:

Given A person has Salary scale of 10000-100-20000. Find his total salary after 6 years  and 10 months

• Here a =10,000, d = 100, n = 6 yrs 10 months
• We know that Sn = n/2 (2a + (n – 1 )d)
•                             = 6/2 (2(10000) + (6 – 1)100)
•                             = 3 (20000 + 500)
•                            = 61,500
•   So S = 61,500 x 12 = 7,38,000
• Now we need to find for 10 months.
• So  an = a + (n – 1)d
•            = 10000 + (6 – 1)d
•            = 10,000 + 500
•            = 10,500
• So salary will be 10,500 x 10 = 1,05,000
• Therefore total salary will be 7,38,000 + 1,05,000
•                                              = Rs 8,42,000
