X can do a piece of work in 10 days and Y can do the same work in 15 days if X and Y work for 2 days together after that X left the work then find the time taken by Y to complete the remaining work.1. 10 days2. 12 days3. 8 days4. 15 days |
|
Answer» Correct Answer - Option 1 : 10 days Given: Time taken by X to complete the work = 10 days Time taken by Y to complete the work = 15 days They both work together for 2 days Formula used: Efficiency = Total work/Time taken Calculation: LCM of 10 and 15 = 30 = Total work Efficiency of X = 30/10 units/day ⇒ 3 units/day Efficiency of Y = 30/15 units/day ⇒ 2 units/day Total work done by X and Y together in 2 days = (3 + 2) × 2 units ⇒ 10 units Work remaining = (30 – 10) units ⇒ 20 units Time taken by Y to complete the work = 20/2 udays ⇒ 10 days ∴ Time taken by Y to complete the remaining work is 10 days |

Ram completes a work in 16 days, Laxman takes 20 days to complete the same work. They work together for 4 days and then Ram leaves. In how many more days will Laxman complete the work?1. 162. 133. 124. 11 |
|
Answer» Correct Answer - Option 4 : 11 Given: Ram completes a work in 16 days Laxman completes the same work in 20 days Both worked together for 4 days Ram left the work after 4 days Formula Used: Work = Efficiency × Time Calculation: Let Laxman will complete the work in D more days Total work is LCM of 16 days and 20 days ⇒ Total work = 80 Efficiency of Ram = 80/16 ⇒ 5 Efficiency of Laxman = 80/20 ⇒ 4 Both worked together for 4 days and then Ram left and the remaining work is completed by Laxman in D days 4(5 + 4) + D × 4 = 80 ⇒ 4 × 9 + 4D = 80 ⇒ 4D = 80 – 36 ⇒ D = 44/4 ⇒ D = 11 ∴ In 11 more days Laxman will complete the work. |

Economic backwardness of a region is (241) by the coexistence of unutilized (242) on the one hand and (243) natural resources on the other. Economic development essentially means a process of (244) change whereby the real per capita income of an economy (245) over a period of time. Then a simple but meaningful question arises, what causes economic development? Or what makes a country developed? This question has absorbed the (246) of scholars of socio-economic changes for decades. Going through the (247) history of developed countries like America, Russia and Japan, man is essentially found as (248) in the process of economic development. Japan, whose economy was (249) damaged from the ravages of the 2nd world War, is the example of our time to (250) kingdom role in economic development.A. ExhaustiveB. UnexploitedC. AbundantD.
