Directions: Read the following information to answer the question.
Answer : 112
Solution: LCM of 4,7,8 is 56
The smallest 3 digit no. that can be divided by 4,7,8 will also be divided by 56.
(56*2=112)----3 digit no.
So 112 is the smallest 3 digit no.
i.e. closest to 100 and of 3 digits.
Hence proved
Directions: Read the following information to answer the question.
Answer: 40
Explanation: formula is: (X!/prime no.)+(X/prime no^2)……..continued till prime no. don’t get bigger than X
NOTE: take the whole value you get ondividing.
83/3+83/9+83/27+83/81=27+9+3+1=40
Hence proved.
Directions: Read the following information to answer the question.
(8^5)/7…..here 8/7=1 remainder.
Directions: Refer the following data to answer the questions given below.
Milk in 1 litre mixture in 1st can = 3/4 litre.
Milk in 1 litre mixture in 2nd can = 1/2 litre.
Milk in 1 litre final mixture = 5/8 litre.
By rule of alligation we have required ratio 5 : 8
Directions: Refer the following data to answer the questions given below.
Let cost price of milk be Rs 1 per liter, then S.P of mixture is also Rs 1 per liter
Now CP of mixture be = 1 - ( 20 % of Rs 1 ) = 1 - ( 20 * 1 / 100 ) = 80 / 100 = Rs 4 / 5
