Answer 1

48.25 x 150+32 x 16.5 - 125 x 10.5 = 6453

Option (c) is correct.

Given:

• 48.25 x 150+32 x 16.5 - 125 x 10.5

To find:

• Solution is
• (a) 6200
• (b) 7500
• (c) 6453
• (d) 7100
• (e) 6700

Solution:

Concept to be used: Apply BODMAS rule.

Step 1:

Identify the terms of multiplication.

48.25 x 150 + 32 x 16.5 - 125 x 10.5

Step 2:

According to BODMAS rule, Multiply the highlighted terms first.

$48.25 \\ \times 150 \\ - - - - - \\ \: \: \: \: \: \: \: \: 0000 \\ \: \: \: \: 24125\times \\ \: \: \: \: 4825\times \times \\ - - - - - \\ 7237.50 \\ - - - - -$

like this Multiply others two terms too.

$32 \times 16.5 = 528$

and

$125 \times 10.5 = 1312.5$

Step 3:

Write the terms with sign in the expression

$= 7237.50 + 528 - 1312.5$

or

$= 7765.5 - 1312.5$

or

$= 6453$

Thus,

48.25 x 150+32 x 16.5 - 125 x 10.5 = 6453

Option c is correct.
