What is the unit digit in the product (365 x 659 x 771)?

Unit digit in 34 = 1 Unit digit in (34)16 = 1

Unit digit in 365 = Unit digit in [ (34)16 x 3 ] = (1 x 3) = 3

Unit digit in 659 = 6

Unit digit in 74 Unit digit in (74)17 is 1.

Unit digit in 771 = Unit digit in [(74)17 x 73] = (1 x 3) = 3

Required digit = Unit digit in (3 x 6 x 3) = 4

A 5000 metre long train crosses a platform in 25 seconds while it crosses a single pole in 10 seconds. What is the length of the platform?

Speed=500/10

Speed=50m

Let the length of platform be x metres

X=1250-500

X=750
