"233",
"960",

] | C | Explanation:
Total salary of 8 workers and supervisor together = 9 × 430 = 3870
Now total salary of 8 workers = 3870 − 870 = 3000
Total salary of 9 workers including the new supervisor = 9 × 440 = 3960
Salary of the new supervisor = 3960 − 3000 = 960

In a certain store, the profit is 320% of the cost. If the cost increases by 20% but the selling price
remains constant, approximately what percentage of the selling price is the profit | [
"81%",
"None of above",
"90%",
"71%"
] | D | Explanation:
Let C.P.= Rs. 100.
Then, Profit = Rs. 320,
S.P. = Rs. 420.
New C.P. = 120% of Rs. 100 = Rs. 120
New S.P. = Rs. 420.
Profit = Rs. (420 - 120) = Rs. 300
Required percentage = (300/420) * 100
= 71.40%(approx) =71%
