Question

4. Find the smallest number which when divided by 14, 28, 35, and 55 leaves 5 as remainder
in each case.

5. Three children go for a walk. Their steps measure 25 cm, 35 cm and 45 cm respectively.
At what distance from the starting point will they ston off together again?​

Answer 1

Answer:

Since we have to find the dividend we will find the LCM of given numbers

14=7*2

28=4*7

35=7*5

55=5*11

The LCM is 7*4*5*11=1540

Since this number leaves remainder of 5 we will add 5 to this number so the answer is 1540+5

1545
