If 42 persons consume 144 kg, of wheat in 15 days, then in how many days will 30 persons consume 48 kg of wheat ?
Using, $$\frac{M_1D_1}{W_1}$$Â $$=\frac{M_2D_2}{W_2}$$, where $$M$$ is number of men, $$D$$ is number of days and $$W$$ is work done.
Let in $$x$$ days, 30 persons will consume 48 kg of wheat.
According to ques,
=> $$\frac{42\times15}{144}=\frac{30\times x}{48}$$
=> $$\frac{7\times5}{8}=\frac{5x}{8}$$
=> $$x=7$$
$$\therefore$$Â 30 persons will consume 48 kg of wheat in 7 days.
=> Ans - (B)
