Let x be total \(\frac{items}{week}\),
Selling Price (SP) will be 60x,
Cost Price (CP) will be [40x+4000 (extra 1000 for profit)]
So,
40x + 4000 = 60x
20x = 4000
x=200.
The number of units he should produce and sell in order to make a profit of at least \(₹\)1000 per week is 200 So the correct option is (D)
A man buys a watch for Rs. 1950 in cash and sells it for Rs. 2200 at a credit of 1 year. If the rate of interest is \(10\%\) per annum, the man.
A man sells Rs. 5000, \(12\%\) stock at 156 and invests the proceeds partly in \(8\%\) stock at 90 and the balance in \(9\%\) stock at 108. He thereby increase his income by Rs. 70. How much of the proceeds were invested in each stock?
