The correct option is (A): Rs. 2400
Explanation:
Assume: Salary for full day work = \(Rs. 2x\),
So, half day salary = \(Rs. x\) and absent penalty = \(Rs. 15\)
The worker was absent for 4 days, so received full pay for 18 days, and he was late for 8 days.
So, according to ques,
\(⇒\) \((18 \times 2x) + (8\times x) (4 \times 15) = 1700\)
\(⇒\) \(36x + 8x - 60 = 1700\)
\(⇒\) \(x = \frac{1760}{44} = 40\)
So, Salary paid to the worker who arrived on time each day and had no absences = \(30 × 2 × 40 = Rs. 2400\)
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?
