Directions: Read the following information to answer the question.
Answer:38
Explanation: hcf of 48,144 and 264 is 12 .
For mango 48/12=4,for jackfruit 144/12=12,for coconut 264/12=22
So 4+12+22=38
Hence proved
Directions: Read the following information to answer the question.
Answer:16
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
So here (18/2+18/4+18/8+18/16)=9+4+2+1=16
Hence proved.

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.
Answer:32
Explanation:the no. of zeros at the end of n!=[n/5]+[n/5^2]+[n/5^3]+…..
So,[130/5]+[130/25]+[130/125]+…..=26+5+1+0…=32
Hence proved.
Directions: Read the following information to answer the question.
What is the last digit or units’ digit of 244?
Answer:6
Explanation: cyclicity of 2 is 4.so power 44 when divided by 4 gives remaionder 0 .
Note:If the remainder comes out 0 in any case then the unit digit will be the last digit of a cyclicity number.
Here last digit of cyclicity of 2 is 6.
Hence proved.
