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

Hira has 30 bangles, 18 of which are pink and 12 of which are white. Saher has 20 bangles, all of them either pink or white. If the ratio of the pink bangles to the white bangles is the same for both Hira and Saher, then Hira has how many more pink bangles then Sahar?

3 X = 3 (4 )= 12 pink bangles

Hira have: 18 - 2 = 6 bangles more than Sahar.
