Answer:

Let us consider the number to be

First number = x

Second Number = x+1

Third Number = x+2

According to the question, We get

2x + 3(x+1) + 4(x+2)-74

2x+ 3x+3+4x+8=74

9x + 11=74

9x = 74-11

9x = 63

x = 63/9

x= 7

Therefore,

The First Number = x = 7

The second number = x+1 = 7+1 = 8

the third Number = x+2 = 7+2 = 9

Hence The first,Second & third Number are 7,8 & 9 respectively

Given : three consecutive integers are such that when they, are taken in increasing order and multiplied by 2,3 and 4 respectively, they add up to 74.

To Find : The numbers respectively

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀⠀

❒ Let the numbers be x, x + 1, x + 2 respectively

 \\

{ \underline{ \bf{ \bigstar \: According  \: to \:  the \:  question  : }}}

  • When the numbers are multiplied with the numbers 2,3,4 respectively they add up to 74

 \\

{ \underline{ \frak{As \:  we \:  know \:  that  \dag}}}

  • The numbers are x , x + 1 and x + 2 so, now let's frame an equation according to the question

 \\

{ \underline{ \bf{ \star \: Framing  \: an  \: equation  \: we \:  get : }}}

 \\

{ : \implies} \sf \: (x \times 2) +  \{(x + 1) \times 3 \} \:  +\{(x + 2) \times 4 \}  = 74 \\  \\  \\ { : \implies} \sf 2x + 3x + 3 + 4x + 8 = 74   \\  \\  \\ { : \implies} \sf 9x + 11 = 74 \\  \\  \\ { : \implies} \sf 9x = 74 - 11     \\  \\  \\ { : \implies} \sf 9x = 63 \\  \\  \\ { : \implies} \sf x =  \cancel \frac{63}{9}  \\  \\  \\ { \dashrightarrow} \sf { \pink{ \underline{ \boxed{ \frak{x = 7}}} \star}}

 \\

Hence The numbers are,

⠀⠀⠀

⠀⠀⠀⠀☆ x = (7) = 7

⠀⠀⠀☆ x + 1 = ( 7 + 1 ) = 8

⠀⠀⠀⠀☆ x + 2 = ( 7 + 2 ) = 9

 \\

{ \underline{ \rm{ \therefore the \: numbers \: are \: 7 , 8 \: and \: 9 \: respectively}}}
