There are 100 possibilities for the last two digits [ if we include
00].....therefore....you have 1/100 chance [1 % ] chance of
choosing the correct one.....
<span>In this question you need to find the lowest common multiple. I like to
do it the factor tree way:<span>
<span>
15
9</span>
/ \
/ \
3 5
3 3
See how there are both a 3 in the 15 factor tree
and there is at least on three in the 9 factor tree. So when you find the LCM,
you combine the two threes from the different factor trees like this:
3 x 5 x 3 = 45
So every 45 minutes the bus would be at the bus
stop together
Now simply add the 45mins onto the 1:25
<span>Answer: 2:10 </span></span></span>
Answer:
52.5 kg ANS
Step-by-step explanation:
Weight of a pile of sand = 90kg
Ratio of weight of sand in three bags = 2:3:7
Let the weight be 2x kg, 3x kg, 7x kg respectively A.T.Q.
= 2x + 3x +7x = 90
= 12x = 90
= X= 90/12
= X = 7.5 kg
Weight of sand in medium bag =
= 3 × 7.5
= 52.5 kg ANS
I hope this answer is correct
