Answer 2

Answer:

1)Salary = Rs 12750

Find the amount saved:

Amount saved = 22% of his salary

Amount saved = 22% x Rs 12750

Amount saved = 0.22 x 12750 = Rs 2805

Find the amount spent:

Amount spent = Salary - Amount Saved

Amount spent = 12750 - 2805 = Rs 9945

Answer: His expenditure is Rs 9945

2)Let the total no of students be valued as 100%.

Then, 94% of it is present.

SO,(100-94) = 6 % of them are absent .

No of students who were absent  = 174

So, we can say , 6% equals to 174

So, 1 % equals to 174/6 = 29

And 100% equals to = 29*100 = 2900

Answer: Hence, total strentgh is 2900
