Question

What value will you obtain if twenty five per cent of 2340 is subtracted from four-ninth of square of 36?

Answer 1

STEP 1: Form equation:

twenty five per cent of 2340 is subtracted from four-ninth of square of 36

⇒ 4/9 x 36² - 25% x 2340

.

STEP 2: Solve x:

4/9 x 36² - 25% x 2340

⇒ 4/9 x 1296 - 0.25 x 2340

⇒ 576 - 0.25 x 2340

⇒ 576 - 585

⇒ -9

.

Answer: -9

Answer 2

According to the question ,

$\mathbf{\frac{4}{9} \: \: of \: \: ( 36 )^{2} - [ 25\% \: \: of \: \: 2340 ] } \\ \\ \\ = > \frac{4}{9} \times {(36)}^{2} - [ \frac{25}{100} \times 2340] \\ \\ \\ = > \frac{4}{9} \times 36 \times 36 - [ \frac{1}{4} \times 2340]\\ \\ \\ = > 4 \times 144 - [ 585] \\ \\ \\ = > 576 - 585 \\ \\ \\ = > - 9$
