Sol.
Let total work be 144 units. (LCM)
So, efficiency of Shivam and Maanik are 3 units/day and 2 units/day respectively.
Time taken when both working together =144/5 π‘‘π‘Žπ‘¦π‘ 
Time taken by Amit to finish work alone =144/5 × 5/6=24 π‘‘π‘Žπ‘¦π‘ 
So, efficiency of Amit =144/24=6 𝑒𝑛𝑖𝑑𝑠/π‘‘π‘Žπ‘¦
Let Maanik worked for T days.
ATQ
5×𝑇+9×6=144𝑇=90/5=18 π‘‘π‘Žπ‘¦π‘ 
Total work done by Maanik =18×2=36 𝑒𝑛𝑖𝑑𝑠
So, required part of work =36/144=1/4

S7. Ans. (b)
Sol.
Let the labourer present for x days.
ATQ
170×π‘₯−40×(35−π‘₯)=3640
170π‘₯−1400+40π‘₯=3640
210π‘₯=5040
π‘₯=24
So, required no. of days =35−24=11 π‘‘π‘Žπ‘¦π‘
