So, product = (2 X 4 X 4) = 32.
What value should come in place of the question mark (?) in the following question?
2000 ÷ 10 + 250 × 2 �...
1120 / √x = 80 Then x = ?
- What will come in place of (?), in the given expression.
144 ÷ √36 + 13² – 100 = ? Find the simplified value of the given expression:
(12 ÷ 3 of 2 + 11 of 2) ÷ 4
25% of 300 + √(?) = 35% of 600 - 15% of 300
45% of 1020 + ?% of 960 = 747
- What will come in the place of question mark (?) in the given expression?
121/? = ?/144 6% of 520 + 5% of 620 = ?
