Question
Which of the following options is the closest
approximate value that should come in place of the question mark (?) in the following equation? 14.99 ÷ 5.01 x 9.99 – 6.99 = ?ÂSolution
Step 1: Approximate the values
14.99 ≈ 15
5.01 ≈ 5
9.99 ≈ 10
6.99 ≈ 7
So approximately: (15÷5)×10−7(15 \div 5) \times 10 - 7 ( 15 ÷ 5 ) × 10 − 7 Step 2: Perform operations
15 ÷ 5 = 3  Closest approximate value: 23
3 × 10 = 30
30 - 7 = 23
?% of 320 = 40% of 40 × 5
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
42% of 400 + 38% of 800 + ?2 = 728
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ?- What will come in place of (?) in the given expression.
√324 + √121 – √49 = ? Determine the simplified value of following expression:
0.998 + 0.882 + 0.12Â
√225 + 27 × 10 + ? = 320
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128Â
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
What is the value of 143 + 163 + 183 + … + 303?
