300 students attended the summer camp, and every child was allowed to opt only one activity for the camp. So 100% = 300 1% = 3 The total number of students who opted for Yoga and Painting taken together = (18+12)% = 30% = 30x3 = 90 total number of children who opted for Music and Dance taken together = (24+16)% = 40% = 40x3 = 120 Required answer = 120-90 = 30
255 × 8 + 386 × 5 =? % of 7940
45% of 360 - 160 + ? = √324
56 ÷ 14 × 4 – 316 + ? 2 = 100
323 × 15 + (?)² = 4989
(√1024 + √324)% of 780 = ?% of 260
2197 1/3 + 30% of 1800 = ?× 343 1/3
2 X 25 + (30% of 80) ÷ (10% of 120) = ?
(42% of 1500 + 170) ÷ 4 = ?2 - 52
84% of 800 + 70% of 640 = 14 × ?
√4096 + √3249 = (?)2
