Question

17) We are given a set of 30 buttons such that 5 are black, 5 are yellow, 6 are green, are red, 3 are blue and
7 are pink. If the colour represent: Green=-3, yellow -9, blue = 1. pink 3, black - 6, red = 7. Find the
sum of 30 buttons​

Answer 1

Answer:

-55 is the sum of 30 buttons

Step-by-step explanation:

sum of 30 buttons= 6× -3 + 5× -9 +3×1+7×3+5× -6 +2×7

= -18-45+3+21-30+14

=38-93

= -55

Answer 2

AnswEr :

We're given a set of 30 buttons such that 5 are black, 5 are yellow, 6 are green, 4 are red, 3 are blue and 7 are pink. If the colour represent: Green= -3, yellow = -9, blue = 1. pink = 3, black = - 6, red = 7.

━━━━━━━━━━━━

GivEn :

• Total buttons = 30
• Black button = 5
• Yellow button = 5
• Green button = 6
• Red button = 4
• Blue button = 3
• Pink button = 7

Accordingly,

• Green represents = -3
• Yellow represents = -9
• Blue represents = 1
• Pink represents = 3
• Black represents = -6
• Red represents = 7

To find :

• Sum of all 30. no's = ?

━━━━━━━━━━━━

Step-by-step explanation :

$\star \:{\underline{\boxed{\sf{Black\: buttons : }}}}$

⠀⠀

• No. of button = 5

⠀⠀

• 1 button presents = -6

⠀⠀

$:\implies$ 5 buttons will represents = 5 x -6

⠀⠀

$:\implies$ 5 buttons will represent = -30

⠀⠀

━━━━━━━━━━━━

$\star\:\sf{\orange{\underline{\boxed{\sf{Yellow\: buttons : }}}}}$

⠀⠀

• No. of button = 5

⠀⠀

• 1 button presents = -9

⠀⠀

$:\implies$ 5 buttons will represents = 5 x -9

⠀⠀

$:\implies$ 5 buttons will represent = -45

⠀⠀

━━━━━━━━━━━━

⠀⠀

$\star\: \sf {\green{\underline{\boxed{\sf{Green\: button :}}}}}$

⠀⠀

• No. of button = 6

⠀⠀

• 1 button presents = -3

⠀⠀

$:\implies$ 5 buttons will represents = 6 x -3

⠀⠀

$:\implies$ 5 buttons will represent = -18

⠀⠀

━━━━━━━━━━━━

⠀

$\star\: \sf{\red{\underline{\boxed{\sf{Red\: buttons : }}}}}$

⠀⠀

• No. of button = 4

⠀⠀

• 1 button presents = 7

⠀⠀

$:\implies$ 5 buttons will represents = 4 x 7

⠀⠀

$:\implies$ 5 buttons will represent = 28

━━━━━━━━━━━━⠀⠀

$\star \: \sf {\blue{\underline{\boxed{\sf{Blue\: button :}}}}}$

⠀⠀

• No. of button = 3

⠀⠀

• 1 button presents = 1

⠀⠀

$:\implies$ 5 buttons will represents = 3 x 1

⠀⠀

$:\implies$ 5 buttons will represent = 3

⠀⠀

━━━━━━━━━━━━

⠀⠀

$\star\: \sf{\pink{\underline{\boxed{\sf{Pink \: button :}}}}}$

⠀⠀

• No. of button = 7

⠀⠀

• 1 button presents = 3

⠀⠀

$:\implies$ 5 buttons will represents = 7 x 3

⠀⠀

$:\implies$ 5 buttons will represent = 21

⠀⠀

━━━━━━━━━━━━⠀⠀

Now,

• Sum of 30 buttons :

$:\implies$ Sum of 30 buttons = - 30 - 45 - 18 + 28 + 3 + 21

⠀⠀

$:\implies$ Sum of 30 buttons = - 93 + 52

⠀⠀

$:\implies$ Sum of 30 buttons = - 41

⠀⠀⠀⠀

Therefore, sum is -41
