Answer 2

$\large{\boxed{\green{Question}}}$

23% of 8040 + 42% of 545= ?% of 3000​

$\large{\boxed{\red{Answer}}}$

Let X = ?

➡️23/100 × 8040 + 42/100 × 545 = X/100 × 3000

➡️0.23 × 8040 + 0.42 × 545 = X/100 × 3000

➡️1849.2 + 228.9 = X/100 × 3000

➡️2078.1 = X/100 × 3000

➡️2078.1/3000 = X/100

➡️2078.1/3000 × 100 = X

➡️X = 69.27

So, the answer is, 23% of 8040 + 42% of 545= '69.27'% of 3000​
