The following bar graph shows the number of kids who like different fruits.
What percentage of kids like bananas or apples?
What is the value of \( (1 \div 4) + (1 \div 6) - \bigl( (1 \div 8) \div (1 \div 4) \bigr) \) ?
P1 and P2 can do a piece of work together in 14 days, P2 and P3 can do the same work together in 21 days, while P3 and P1 can do it together in 42 days. How much work can all the 3 together do in 12 days?
\( \frac{5}{6} \)
\( \frac{5}{7} \)
\( \frac{6}{7} \)
\( \frac{3}{7} \)
N1 alone can do 20% of a piece of work in 6 days, N2 alone can do 20% of the same work in 4 days, and N3 alone can do 50% of the same work in 12 days. In how many days can they complete the work, if all of them work together?
10 days
\( \frac{120}{3} \) days
8 days
\( \frac{120}{17} \) days
