The diagram represents the number of students studying

36% of 250 + 26 ÷ 2 × ? = 207

What will come in the place of question mark (?) in the given expression?

45% of (√6400 × 5) = ? + 111 

(7² × 5² + 1555 )/(79+60) = 2000 ÷ ?

Solve the following equation.

143 + 14.3 + 1.43 + 0.143 + 0.0143 =?

[(40)² ÷ 32 × 4] ÷ 50 = ?

Find the simplified value of the given expression.

{12.75 × √64 + 13.5 × √(√256)} ÷ 6 + 49.5 ÷ 5.5 

10 × 100 ÷ 5 + 9 = ?

What will come in the place of question mark (?) in the given expression?

40% of 150 - ?% of 75 = 15 × 1.6

Determine the value of ‘x’ if x% of 500 plus {1250 ÷ x of 10} × 5 equals 130

(3/7) x 868 + 25% of 240 = (? + 65)
