Answer» Correct Answer - Option 1 : 10000 Let the sales he made be Rs. x If sales are less than 1 lakh, he would have received only basic pay which should be same for half the sales. ∴ Sales > 1 lakh Let us assume 200000 > x > 100000 Half the sales will be less than 100000 ∴ Salary received them = Basic pay = Rs. 15000 Salary received for sale of Rs. x = Basic pay + Commission of 10% ⇒ 50000 = 15000 + (x – 100000) × 10/100 [∵ Commission is paid on every penny above 1 lakh] ⇒ x = 450000 It contradicts the assumption Let us assume x > 200000 Salary received = Basic pay + Commission of 10% + Bonus of 20% ⇒ 50000 = y + (x – 100000) × 10/100 + (x – 200000) × 20/100 100000 = y + 0.3x ---- 1 Maximum value of x = 100000/0.3 = Rs. 33333 1/3 ∴ Half of sales is always less than Rs. 200000 ∴ No bonus is paid when sales is halved ⇒ 15000 = y + 10/100 × (x/2 – 100000) ⇒ 25000 = y + 0.05x ---- 2 Equation 1 – Equation 2 ⇒ 75000 = 0.25x ⇒ x = 300000 Substituting in equation 1 ⇒ y = Rs. 10000 ∴ The value of y is Rs. 10000. |
