Practicing Success
40 people were employed who could together make 60 toys in 8 hours, but 8 people left just before work was to begin. How many toys could then be made in 12 hours? |
70 52 60 72 |
72 |
Formula to be used here, \(\frac{M_1\;×\;H_1}{M_2\;×\;H_2}\) = \(\frac{W_1}{W_2}\) where, M = No. of Men, H = No. of hours, W = Work ⇒ Putting values in the formula, ⇒ \(\frac{40\;×\;8}{32\;×\;12}\) = \(\frac{60}{W_2}\) ⇒ \( { W}_{2 } \) = 72. |
