1.	If the sum of two consecutive numbers is 21, the lesser one is:A)9 ,B)10,c)11,d)12
Answer» Given The sum of two CONSECUTIVE numbers is 21 . To FIND The lesser number $\sf\huge\bold{\underline{\underline{{Solution}}}}$ Option (B) 10 Let us ASSUME that the first consecutive number be 'x' second consecutive number be 'x+1' According to the question=> The sum of two consecutive numbers is 21 Then, x+(x+1)=21 =>x+x+1=21 =>2x+1=21 =>2x=21-1 =>2x=20 =>x=20÷2 =>x=10 X is 10 & x+1=10+1=11 Compare both numbers :- 10 & 11 We observe that 10 is the lesser number or 11 is the greater number. Check:- =>x+(x+1)=21 =>10+11=21 Extra information=> Consecutive numbers are those number which comes after one another or in SIMPLE words we can SAY they come in a sequential form. e.g, 1+2+3+4+5 are consecutive numbers. if x is 1 , then x+1 is 2 ; x+2 is 3 ;x+3 is 4 and x+4 is 5 and so on.

If the sum of two consecutive numbers is 21, the lesser one is:A)9 ,B)10,c)11,d)12

Answer»

The sum of two CONSECUTIVE numbers is 21 .

The lesser number

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Let us ASSUME that the first consecutive number be 'x'

second consecutive number be 'x+1'

According to the question=>

The sum of two consecutive numbers is 21

Then, x+(x+1)=21

=>x+x+1=21

=>2x+1=21

=>2x=21-1

=>2x=20

=>x=20÷2

=>x=10

X is 10 & x+1=10+1=11

Compare both numbers :- 10 & 11

We observe that 10 is the lesser number or 11 is the greater number.

=>x+(x+1)=21

=>10+11=21

Consecutive numbers are those number which comes after one another or in SIMPLE words we can SAY they come in a sequential form.

e.g, 1+2+3+4+5 are consecutive numbers.

if x is 1 , then x+1 is 2 ; x+2 is 3 ;x+3 is 4 and x+4 is 5 and so on.
