Question
Solution
The upper-left element gets laterally inverted in first, third, fifth. .... steps; the upper-right element gets rotated through 180o is first, fourth, seventh,.... steps; the lower-left element gets laterally inverted in second, fourth, sixth, ... steps; the lower-right element gets rotated through 180o in third, sixth,... steps and the pin at the middle-right position gets laterally inverted in every second step.
Find the simplified value of the given expression:
(12 ÷ 3 of 2 + 11 of 2) ÷ 4
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
What will come in the place of question mark (?) in the given expression?
?2 - 222 = 900 ÷ 4 - √1089
Simplify: 0.004 × 0.5
420 ÷ 7 + 140 % of 20 + ? × 13 = 18 × 15
150% of ? + 280 ÷ 35 = 132 - 122 + 7
756 + 432 – 361 + ? = 990
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
What value should come in the place of (?) in the following questions?
√16 * ? = √144 + (18 * 4 ÷ 3)
√0.49 + √6.25 + √1.44 + √1.21 =? % of 125
