Question

water stars to drip out of two taps. A drop of water comes out of one tap every 7seconds and every 5 seconds out of the Other tap .at a particular instant to drop from the two taps
fall together after what time will they fall together next time? Why should we start to save water and how?​

Answer 1

Answer:

after 35 secs  drip out of two taps will  fall together

Step-by-step explanation:

A drop of water comes out of one tap every 7seconds and every 5 seconds out of the Other tap

to find the time drip out of two tap will  fall together we need to find LCM of both the time

7 sec & 5 sec

7 & 5 are prime numbers

so LCM = 7 * 5 = 35

=> after 35 secs  drip out of two taps will  fall together

Answer 2

Step-by-step explanation:

1. So we have to find Lcm here.so we just have to find it by any methhod like prime factorization.That is 7*5=35. 35 is the right answer
