Question
What is the difference between average number of
article sold by B and D on all the four days? Read the following information carefully and answer the given questions: Table given below gives information about number of articles sold by four different people (A, B, C and D) on four different days (Monday, Wednesday, Friday and Saturday).Solution
Average number of article sold by B on all the four days = (102 + 85 + 140 + 117)/4 = 111 Average number of article sold by D on all the four days = (90 + 113 + 112 + 85)/4 = 100 Required difference = 111 – 100 = 11
Evaluate:
7.5 + 12 ÷ (4 × 1.5) − 2.4
22% of 560 + 34% of 2160 × 5/12 =? + 16% of 920
(506 ÷ 22 + 9 × 3) × ? = 900 ÷ 9

10³ = (? – 6) × 320 ÷ 8
7(3/6) of 534 + 262 = 61800 - ?
(150% of 950) ÷ ? = 25
181/8 + 51/4 – 63/8 = ? + 9/2
34 × 5 × 2 ÷ 6 + 7 × 5 + 13 = (?)× 6 – 754
What will come in the place of question mark (?) in the given expression?
?% of 2480 + 15 × 34 = 1440
