Face value is the value of digit itself
? face value of 7 = 7
Place value of 8 = 800
Face value of 8 = 8
? required sum = 800 + 8
121012 = 12 x 10084 + 4
? remainder = 4
92 and 85 are coprime numbers because their HCF is 1.
When a number is divisible by 11, then sum of numbers at even place - sum of numbers at odd place = 0 or divisible by 11.
( x + x + 1 ) - ( 1+ 5 + 0 ) = 11
? 2x - 5 = 11
? x = 8
Units digit in the given product = Units digit of 4 x 8 x 7 x 3
= Units digit of 672
= 2
dividend = divisor x quotient + remainder
= ( 13 x 30) + 12
= 390 + 12
= 402
Position value of 6 = 10000
First whole number is 0 and when any number is multiplied with zero, then result is zero.
Let number be the x.
According to the equation , x - x?7 = 180
? 6x?7 = 180
? x = 210
