Question
In a class, 2/5 of the students are girls and rest are
boys. If 4/9 of the girls and 1/3 of the boys are absent, what part of the total number of students are present?Solution
Let the total number of students in a class be x According to the question, Number of girls = 2x/5 and number of boys = x - 2x/5 = 3x/5 Number of girls who are absent = 2x/5 x 4x/9 = (8x)/45 and number of boys who are absent = 3x/5 x 1x/3 = x/5 Total number of students who are present = x - (8x/45) - x/5 = (45x - 8x - 9x)/45 = (28x/45) The 28/45 part of the students is present in the class
(23 × 8) – (13 × 5) + 67 =? x 6         Â

(190/38) × (55/5) + (306/18) = ?
24% of 400 × 16% of ? = 384
140% of 75 + 152 - 160 = ?
(2500 ÷ √625) × √(42.25) = ? ÷ 4
What will come in the place of question mark (?) in the given expression?Â
(240% of 175 ÷ √16) X 6 + 80% of 400 = ?3 + 179 + 42
Evaluate:
7.5 + 12 ÷ (4 × 1.5) − 2.4
?2 - (40% of 240) = 25 X 5
- What will come in the place of question mark (?) in the given expression?
32% of 74% of ? = 16% of 37% of 180
