Question
Which sequence of mathematical symbols among given
sequences must be inserted in place of the (?) in order to obtain the desired result? (250 ? 75) ? 7 ? 6 ? 50 = 100Solution
(250 ? 75) ? 7 ? 6 ? 50 = 100 (250 – 75) ÷ 7 x 6 – 50 = 100 175 ÷ 7 x 6 – 50 = 100 25 x 6 – 50 = 100 150 – 50 = 100
