rohit kumar   11 years AGO

3*4*2*1=24 i.e last digit 4
3*1*7*8=448 i.e last digit 8
8*7*5=280 i.e last digit 0
so,
for 8474=8*4*7*4=896 last digit 6

Last digit of the Products.

3421 = 3*4*2*1 = 24 -> Last digit= 4
3178 = 3*1*7*8 = 168 -> Last digit = 8
875 = 8*7*5 = 280 -> Last digit = 0

Therefore,
8474 = 8*4*7*4 = 896 -> Last digit = 6

Parveen Soni   11 years AGO

Multiply all digits and write last digit
e.g 3*4*2*1=24 write 4 and similarly for others.
for 8474 we have unit place digit 6 of 8*4*7*4. Hence option 4.

Saurabh keshri   11 years AGO

3*4*2*1=24(unit digit=4)
3*1*7*8=168(unit digit=8)
and 8*7*5=280(unit digit=0)
similarly...
8*4*7*4=896 (unit digit=6)
Hence, option number 4 is correct answer.

Khushboo   11 years AGO

3*4*2*1=24 its last digit is 4 hence 3421 taken as similarly for 3178, 3*1*7*8=168, last digit is 8,and for 875, 8*7*5=280, last digit(digit at ones place)is 0 hence 875 is taken as 0.
Now for 8474, 8*4*7*4=896, last digit is 6 hence answer is 6(option 4).

Multiply each digits and take unit digit.
3*4*2*1 = 24 = unit digit 4
3*1*7*8 = 168 = unit digit 8
Same way,
8*4*7*4 = 896 = unit digit 6 is the answer.

write only unit digit of the product of digits of number.like 4*3*2*1=24 we will take 4 then in same way 3*1*7*8=168 we ll take 8 of this ..8*7*5=280 we ll take 0 hence for 8*4*7*4=896 we ll take 6 hence answer is 6.

3421=4;4*1=4
3178=8;8*1=8
875=0;8*5=40 only 0 is taken
so,
8474=6;4*4=16 only unit place number is taken

prateek jain   11 years AGO

the reason is
we will multiply the one's place digit and hundred's place digit and if we will get the answer in two digits then we will choose the end digit and that will be the answer.
eg. 4*1=4
1*8=8
8*5=40 (in which we will take the last digit. i.e. 0)
4*4=16 (in which we will take the last digit. I.e. 6)
So the answer is 6.

Sagar Jinachandran   11 years AGO

multiplying each digits of the number we get
3*4*2*1=24
taking the last digit of the product=4
similarly
3*1*7*8=168
taking the last digit of the product=8
8*7*5=280 =0
similarly
8*4*7*4= 896
so taking its last digit = 6
