CASELET DI Level 1 Test 11 Welcome to your CASELET DI Level 1 Test 11 Name Email DIRECTIONS (Qs. 1-3) : Read the given information and answer the questions based on that : Working efficiency of Rohan is 20% more than that of Mohit can alone complete a work ‘X’ in 36 days. Mohit and Ganesh together started to complete the work ‘X’ and after 10 days they both left the work and then remaining work is done by Rohan in 15 days. Rohan and Ganesh together started to complete another work ‘Y’ and after working for 12 days they both left the work. Remaining work is done by Mohit alone in 16 days. Raju first completed work ‘X’ and then completed work ‘Y’ in total 38 days. It is given that efficiency of all, in completing work ‘X’ and work ‘Y’ is same. Rohan, Mohit and Ganesh working together completed 1/3rd of work ‘X’, and then Rohan and Ganesh are replaced by Raju. Now remaining of work ‘X’ is completed by Mohit and Raju together. For how many days Mohit worked ? (a) 12 days (b) 10 days (c) 15 days (d) 4 days (e) 7 days None 2. Working efficiency of Rohan is 20% more than that of Mohit can alone complete a work ‘X’ in 36 days. Mohit and Ganesh together started to complete the work ‘X’ and after 10 days they both left the work and then remaining work is done by Rohan in 15 days. Rohan and Ganesh together started to complete another work ‘Y’ and after working for 12 days they both left the work. Remaining work is done by Mohit alone in 16 days. Raju first completed work ‘X’ and then completed work ‘Y’ in total 38 days. It is given that efficiency of all, in completing work ‘X’ and work ‘Y’ is same. Rohan, Ganesh and Raju working simultaneously completed work ‘X’ in ‘n’days and Rohan, Mohit, Ganesh and Raju working simultaneously completed work ‘Y’ in ‘m’ days. Find the value of (m + n). (a) 15 days (b) 10 days (c) 12 days (d) 8 days (e) None of these None 3. Working efficiency of Rohan is 20% more than that of Mohit can alone complete a work ‘X’ in 36 days. Mohit and Ganesh together started to complete the work ‘X’ and after 10 days they both left the work and then remaining work is done by Rohan in 15 days. Rohan and Ganesh together started to complete another work ‘Y’ and after working for 12 days they both left the work. Remaining work is done by Mohit alone in 16 days. Raju first completed work ‘X’ and then completed work ‘Y’ in total 38 days. It is given that efficiency of all, in completing work ‘X’ and work ‘Y’ is same. If Sohan starts the work ‘X’ and leave after 12 days, then Mohit and Ganesh together complete the remaining work in 8 days. What is the ratio of number of days taken by Rohan and Sohan together to complete the work ‘X’ to the number of days taken by Raju, Mohit and Ganesh together to complete the both work ‘X’ and ‘Y’. (a) 3 : 5 (b) 5 : 3 (c) 8 : 7 (d) 1 : 2 (e) 4 : 5 None Time's up
