Wiley Edge Mathematical Order Quiz-3

Using the correct symbols, we have:
Given expression
= 528 ÷ 24 + 43 × 56 – 172
= 22 + 43 * 56 - 172
= 22 + 2408 - 172
= 2430 - 172
= 2258

Using the proper notations in (d), we get the statement as:
92 + 84 ÷ 12 – 75 × 19
92 + 7 – 75 × 19
99 – 75 * 19
99 - 1425 = -1326

From the first option, we will get:
(144 – 12) × 22 ÷ 75 + 65 = 254
⇒ (144 ÷ 12) × 22 – 75 + 65 = 254
⇒ 12 × 22 – 75 + 65 = 254
⇒ 264 – 75 + 65 = 254
⇒ 329 – 75 = 254

From the first option, we get:
345 + 78 – 13 × 95 ÷ 108 = 2057
⇒ 345 × 78 ÷ 13 + 95 – 108 = 2057
⇒ 345 × 6 + 95 – 108 = 2057
⇒ 2070 + 95 – 108 = 2057
⇒ 2165 – 108 = 2057.

625 + 25 – 24 × 135 ÷ 68 = ?
⇒ ? = 625 ÷ 25 × 24 + 135 – 68
⇒ ? = 25 × 24 + 135 – 68
⇒ ? = 600 + 135 – 68
⇒ ? = 735 - 68
⇒ ? = 667.

From the first option, we will get:
(184 – 4) × 82 ÷ 65 + 105 = 3812
⇒ (184 ÷ 4) × 82 – 65 + 105 = 3812
⇒ 46 × 82 – 65 + 105 = 3812
⇒ 3772 – 65 + 105 = 3812
⇒ 3877 – 105 = 3812

Using the correct symbols, we have:
Given expression
= 1564 ÷ 46 + 73 × 24 – 332
= 34 + 73 * 24 - 332
= 34 + 1752 - 332
= 1786 - 332
= 1454

845 + 5 – 24 × 155 ÷ 541 = ?
845 ÷ 5 × 24 + 155 – 540
169 × 24 + 155 – 540
4056 + 155 – 540
4211 – 540
3671.

6x α 5y ⇒ 6x = 5y
and 2y β 3z ⇒ 2y > 3z
⇒ 6x = 5y and y>3z / 2
⇒ 6x = 5y and 5y >15z / 2 ⇒6x> 15z / 2
⇒ 12x > 15z ⇒ 4x > 5z
⇒ 4x > 3z i.e. 4x β 3z

According to the BODMAS rule,
First of all, we start from solving brackets (1223+343) = 1566,
Then, Division 246 ÷ 15666 = 0.157
Then, Subtraction 130 - 0.157 = 129.843
