√324 * 6 – 20% of 180 + ? = 130% of 150
What is the value of 143 + 163 + 183 + … + 303?
(2/?) x (3/16) x (2/15) x 60 = 1/3


154 × 7 + 480 × 5 =?% of 6956
- What will come in the place of question mark (?) in the given expression?
40% of (320 ÷ 4) + 2² X 25 = ? + 42 (5/8 of 480 - 30% of 420)² ÷ (√81 + 25% of 320) = ?
17% of 250 + ? = 108
Simplify the following expression and find the final value:
(18 ÷ 6 of 2 + 7 of 5) ÷ 5
