Find the maximum number of students among them 1001 pens and 910 pencils can be distributed in such a way that each student gets the same number of pens and same number of pencils.

When 3738, 5659 and 9501 are divided by the greatest possible number x, the remainder in each case is y. What is the sum of x and y?

(444% of 521) ÷972=?

$$ \sqrt{749}×0.56+14.38=?$$

1332.89+171.928+17.01 +?²=1690.87

$$ {109.07\sqrt{?}}-{61\over 21.02} ×?=47.96\sqrt{?}$$

111.01 +41.23+(4.96)² +(2.09)²=?

What should be added at least in 1140 so that it becomes a perfect square?
