Question
The efficiency of A, B, C, D are in the ratio of 6 : 5 :
4 : 3. If A and C can do a work together in 6 days. Then How much days B and D will take to complete the same work?Solution
Efficiency of (A+C) = (6+4) = 10 Days taken by (A+C) together to complete the work = 6 days Efficiency of (B+D) = (5+3) = 8 So, B and D will take time = (Total days of (A+C)×Total Efficiency of (A+C))/(Total Efficiency of (B+D)) = (6 ×10)/8 = 60/8 = 7(1/2) days
(400.01% of 149.89) ÷ 49.97 = ?2 ÷ (95.98 ÷ 31.99)Â
210.34 + 16.92² + ?³ = √900.56 * 31.23
1649.98 ÷ 15.48 × 8.12 = ? × 8.16
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
2380.03 ÷ 84.98 x 39.9 = ? + 15.32
41.98% of 2200.031 + 15% of 3999.9 = ?
2387.56 + ? – 2248.14 = 1765.45 – 1574.23
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
2 (1/4)% of 7999.78 + {49.77% of 899.71} + √144.14 - 20% of 1499.83 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
