Rephrasing the question

Rajiv receives base salary each month plus a 7 percent commission on his total sales revenue for that month . What was Rajiv’s total sales revenue last month ?

Let B= Base SalaryLet R = total sales revenueLet P = total pay last month

Commission = 0.07 RP = B + 0.07R

R = ?

P = B + 0.07 R

P - B = 0.07 R

(P – R) / 0.07 = R

Rajiv receives base salary each month plus a 7 percent commission on his total sales revenue for that month . What was rajiv’s total sales revenue last month ?

Let B= Base SalaryLet R = total sales revenueLet P = total pay last month

Commission = 0.07 RP = B + 0.07R

R = ?

1) Rajiv’s total last month pay was Rs. 25000

2) Rajiv’s total last month pay was Rs. 15000 greater than his base salary

According to 1st statement :- P = 25000 (P – B)/0.07 (2500 – B)/0.07

According to 2nd statement :- P - B = 15000 (P – B)/0.07 15000/0.07 = 214285.7
