Vedclass · Answer

(A) Let the distance covered on the first day be $d_1$ and on the second day be $d_2$.Given that $d_2 = 70 \,km$ and the ratio $d_1 : d_2 = 4 : 5$.Therefore,$\frac{d_1}{70} = \frac{4}{5}$.$d_1 = \frac{4 	imes 70}{5} = 4 	imes 14 = 56 \,km$.The distance travelled on the third day is $d_3 = 42 \,km$.The ratio of the distance travelled on the third day to the first day is $d_3 : d_1 = 42 : 56$.Dividing both by their greatest common divisor $14$,we get $42 \div 14 = 3$ and $56 \div 14 = 4$.Thus,the required ratio is $3:4$.

$A$ cyclist,after cycling a distance of $70 \,km$ on the second day,finds that the ratio of distance covered by him on the first two days is $4:5$. If he travels a distance of $42 \,km$ on the third day,then the ratio of distances travelled on the third day and the first day is:
