Question
Which two numbers should be interchanged to make the
given equation correct? 9 + 7 × 5 − 18 ÷ 2 = 3 × 4 − 10 + 45 ÷ 5Solution
9 + 7 × 5 − 18 ÷ 2 = 3 × 4 − 10 + 45 ÷ 5 By the option B, To interchange the 7 and 4, 9 + 4 × 5 − 18 ÷ 2 = 3 × 7 − 10 + 45 ÷ 5 9 + 4 × 5 − 9 = 3 × 7 − 10 + 9 9 + 20 − 9 = 21 − 10 + 9 20 = 20
√65 of 14.97 + √50 = (12.02)2 - ?
