Which smallest number must be added to 2203 so that we get a perfect square? 

The weight of a bucket full of water is 36 kg. If the weight of a half-filled bucket is 21 kg, what will be the weight of the empty bucket?

Direction: what should come in place at question mark(?).

(0.85% of 405) +(2.25% of 550)=?

Direction : What should come in place of the question (?) in the following question.

140% of 450 + 24% of 650 =?

Find the value of given expression.

30 – [40 – {56 – (25 – 13 – 12)}]

12 × 15 + 27 – ? = 28% of 400

Simplification the following equations shown below

The sum of two numbers is 29, the difference between the squares of those numbers is 145. There will be a difference of those numbers.
