Find the cost of manufacturing each article if a manufacturer estimates that on inspection 12% of the articles he produces will be rejected. He accepts an order to supply 80,000 articles at Rs. 8 each. He estimates the profit on his outlay including the manufacturing of rejected articles to be 10%.
If 100 articles are manufactured then 12 will be rejected Total selling price of 88 articles = 88 × 8 = 704 Total cost price = (704 × 100)/110 = 640 cost of manufacturing per article = 640/100 = Rs 6.40
The value of 43-3× (4×6+12/3 ×6-4×5) +4?
√1444 + √729 – √2116 = ?
If x - 1/x = 9, then the value of x² + 1/ x² is:
(23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
(3/7) x 868 + 25% of 240 = (? + 65)
1300% of 2341 + 1200% of 6321 = ?
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
5(? + 2) = 3125
(25)² × 4 ÷ 5 + (3)³ + 48=? + 425
