A) 20 trees
B) 18 trees
C) 24 trees
D) None of the above
Correct Answer: B
Solution :
We have, \[{{M}_{1}}=10,\,\,{{D}_{1}}=2,\,\,{{W}_{1}}=15\] and \[{{M}_{2}}=10-2=8.\,\,{{D}_{2}}=3,\,\,{{W}_{2}}=?\] \[\therefore \,\,\,\,\,\,\,{{M}_{1}}\,{{D}_{1}}\,{{W}_{2}}\,=\,{{M}_{2}}\,{{D}_{2}}\,{{W}_{1}}\] s\[\Rightarrow \,\,\,\,10\times 2\times {{W}_{2}}=8\times 3\times 15\] \[\therefore \] \[{{W}_{2}}=18\] tree Thus, 18 trees will be cut in 3 h.You need to login to perform this action.
