चॉक क्रमश: 2:3 के अनुपात में हैं। डिब्बे में सफ़ेद
चॉकों की संख्या कितनी है ?A chalk box having
45 chalks contain white and green
chalks in the ratio of 2: 3 respectively.
What is the number of white chalks in
the box?​

Answer 1

Solution

★ Let the ratios be 2x and 3x

★ Total number of chalks = 45

★ and Total number of chalks = 2x + 3x

Acc to question

$\implies$ 2x + 3x = 45

$\implies$ 5x = 45

$\implies$ x = $\dfrac{45}{5}$

$\implies$ x = 9

⭐white chalks = 2(9) = 18

⭐Green chalks = 3(9) = 27

#Verification

⟶Total number of chalks = white + green

⟶Total number of chalks = 27 + 18 = 45

Let the no. of white and green chalk be 2x and 3x
A/Q
2x+3x=45
=>5x=45
=>x=45÷5
Hence,x=9

So,the no. of white chalk =2x=2×9=18 green chalks.
