|
A |
10,000 | 2,000 |
18,000 |
| B | 6,000 | 20,000 |
8,000 |
If the unit sale price of Pencil, Eraser and Sharpner are Rs 2.50, Rs 1.50 and Rs 1.00 respectively, and unit cost of the above three commodities are Rs 2.00, Rs 1.00 and Rs 0.50 respectively, then,
(i) Total revenue of market A is
(a) Rs 64,000 (b) Rs 60,400
(c) Rs 46,000 (d) Rs 40,600
(ii) Total revenue of market B is
(a) Rs 35,000 (b) Rs 53,000
(c) Rs 50,300 (d) Rs 30,500
(iii) Cost incurred in market A is
(a) Rs 13,000 (b) RS30,100
(c) Rs 10,300 (d) Rs 31,000
(iv) Profit in market A and B respectively are
(a) (Rs 15,000, Rs 17,000) (b) (Rs 17,000, Rs 15000)
(c) (Rs 51,000, Rs 71,000) (d) (Rs 10,000, Rs 20,000)
(v) Gross profit in both market is
(a) Rs 23,000 (b) Rs 20,300
(c) Rs 32,000 (d) Rs 30,200
Solution: (i) Answer (c)
Total revenue for market A
= 10,000×2.50 + 2000×1.50 + 18000×1.00
= Rs 46000
(ii) Answer (b)
Total revenue for market B
= 6,000×2.50 + 20,000×1.50 + 8000×1.00
= Rs 53000
(iii) Answer (a)
Cost incurred in market A
= 10,000×2.00 + 2000×1.00 + 18000×0.50
= Rs 31,000
(iv) Answer (a)
= 6,000×2.00 + 20,000×1.00 + 8000×0.50
= Rs 36,000
Profit in market A = Rs 46000 – Rs 31000 = Rs 15000
Profit in market B = Rs 53000 – Rs 36000 = Rs 17000
(v) Answer (c)
Gross profit = Profit in market A + Profit in market B
= Rs 15000 + Rs 17000
