Answer 1

Answer: rs. 3515

Step-by-step explanation:

Assuming that employees all salary spent on foodgrains and other items.

• Ratio of expenditure on foodgrains and other items = 2:5
• 25900/7 = 3700 ( 7=2+5)
• Expenditure of Foodgrain : 2 X 3700 = rs 7400
• Expenditure of other items : 5X3700 = rs 18500
• Price increase on foodgrain : 10% of rs 7400
• Price increase on foodgrain : rs 740
• Price increase on other items : 15% of rs 18500
• price increase on other items : rs 2775

• Salary hike = rs 740 + rs 1850 = rs 3515.
