Find the simplified value of the given expression.

(1/4) of {6⁴ - 28 x 15 + 13 x 16 - 12.5 of 12²}

Find the simplified value of the given expression:

8 of 7 ÷ 2 × 5² + √36 – 10

55.55% of 30000 – 1111 = ? × 1111

6612 ÷ 19 - ?% of 240 = -2196

540 ÷ 6 + 25 % of 120 + ? * 8 = 72 * √9

134% of 1250 – 46% of 2120 = 4 × ?

Find the simplified value of the given expression:

{(1 x 2) + (3 + 4) - (5 x 6) + (7 + 8) - (9 x 10)}

4387897 – 3286871 – 51926 = ?

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

{(60% of 250) + √144} ÷ (3² - 4) = ?

25% of 160 × 18 = ? – 24
