Question
'A' and 'B' alone can complete a work in 10 days and 15
days, respectively. If they worked together and total wage received by them to complete the work is Rs. 600, then find the wage received by 'A'.Solution
Let total work = 30 units {LCM of 10 and 15} Efficiency of 'A' = 3 units per day Efficiency of 'B' = 2 units per day Since, they completed the whole work together therefore ratio of wage received by them will be same as the ratio of their efficiencies. So, Required wage received by 'A' = {3/(3 + 2)} X 600 = Rs. 360
36.76 + 2894.713 + 34965.11 =?
(320 + 342 + 530 + 915) Γ· (20 + 22 β x + 18) = 43, then the value of x is:
13 X ? = 85 X 4 + β81 + 2
β 729 Γ 5 β 220 % of 15 + ? = 120% of 160
(2197)1/3 + (18)2 β 121 = ? β 69 Γ 5
447.8 × 441.2 ÷ 445 = 44 × 44?
(?) + (35)2 = (140)2 – (80)2 + 20% of 5480
7, 8, 12, 21, 37, ?
- Determine the final value of this expression:
(1/5) of {5β΄ - 24 Γ 14 + 12 Γ 18 - 10.5 of 10Β²} 7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
