Question
If 6 women can complete a work in 3 days, and 9 girls
can complete the same work in 2 days, then find the time taken to complete the same work by 8 women and 6 girls?Solution
6 women can complete a work = 3days 1 woman can do a work = 6Γ3=18days 9 girls can complete the same work=2days 1girl can do a work = 2Γ9=18days AB 1818 18T.W 11 Efficiency (8 women and 6 girls) can do this work = 18/8Γ1+6Γ1 =18/14=9/7days.
√3598 × √(230 ) ÷ √102= ?
15% of 2400 + (β 484 β β 256) = ?
(13)2Β - 3127 Γ· 59 = ? x 4
6269 + 0.25 × 444 + 0.8 × 200 = ? × 15
...(53 + 480 Γ· 4)% of 20 = ?% of 70
Find the simplified value of the following expression:
62 + 122 Γ 5 - {272 + 162 - 422}
(15 Γ 225) Γ· (45 Γ 5) + 480 = ? + 25% of 1240
β [? x 11 + (β 1296)] = 16
11 Γ 25 + 12 Γ 15 + 14 Γ 20 + 15 = ?
