Question
 In a class, 40 like coffee, 50 like tea, 20 like both.
Find number of students who like neither if total is 100.Solution
ATQ,
|C∪T| = 40 + 50 − 20 = 70.
Neither = 100 − 70 = 30.
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
140% of 9/8 of ? = 108% of 2800
4.56 + 56.4 + 64.5 = ? + 10.46
- What will come in the place of question mark (?) in the given expression?
?² = 28% of 35% of 4500 12.5% of (100 + ?) = 40
What will come in the place of question mark (?) in the given expression?
? = 12.5% of 25% of 20% of 1280 + 1248
(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 (1/3) = 82
Solve for the ?
What will come in the place of question mark (?) in the given expression?
(437 + ? - 167) x 2.5 = 875(22% of 1500 + 15% of 2200) = ? x 11
