Answer 1

Step-by-step explanation:

let the number X and X + 1

x + x + 1 = 63

2 x = 62

x = 62 /2 =31

one no=31

other=x+1=32

Answer 2

ANSWER..

let the no. of notes of rs 10 be x

let the no. of notes of rs 20 = 50-x

10x-(50-x) 20 =800

10x-100-20x=800

10x =200

x=20

no.of rs 10 notes 20

no.of rs 20 notes = 50-x

=30
