Total no. of students = 1600 Boys = 1600 x (23/40) = 920 and Girls = 1600 x (17/40) = 680 45% of boys who got passed = 920 x (45/100) = 414 50% of girls who got passed = 680 x (50/100) = 340 Therefore no. of students who got failed = 1600 - (414+ 340) = 846 Required % = [(846/1600)] x 100 = 52.87% approx.
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
Find the simplified value of the given expression.
{12.75 × √64 + 13.5 × √(√256)} ÷ 6 + 49.5 ÷ 5.5
(√7225 x √1225)/(√625) = ?
The value of {5 − 5 ÷ (10 − 12) × 8 + 9} × 3 + 5 + 5 × 5 ÷ 5 of 5 is:
(8.6 × 8.6 + 4.8 × 4.8 + 17.2 × 4.8) ÷ (8.62 – 4.82 ) = ? ÷ 19
390/? = √256 + 3.5
Find the simplified value of the given expression:
224 ÷ 4 + 7 X 36 - 8 of 15 + 162 - 300
2/5 of 3/4 of 7/9 of 7200 = ?
√? + √1296 + √729 = 464/4
