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

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
