Question
Out of the four given equations, the first three are
solved based on a certain system. Find the correct answer for the unsolved fourth equation on the same basis. 3 & 7 = 64 6 & 6 = 109 9 & 8 = 217 10 & 9 = ?Solution
Given equations, 3 & 7 = 64 → 3 × 7 × 3 + 1 = 64 6 & 6 = 109 → 6 × 6 × 3 + 1 = 109 9 & 8 = 217 → 9 × 8 × 3 + 1 = 217 For the fourth equation: 10 & 9 → 10 × 9 × 3 + 1 = 271
- Find the simplified value of following expression:
0.998 + 0.882 + 0.12 ?2 × 25 = 42 × 21 + 172Â
- What will come in the place of question mark (?) in the given expression?
389 + 641 - ? = 180 X 2 9 × 4 ? ÷ 16 = 144
(√1024 + √324)% of 780 = ?% of 260
What value should come in the place of (?) in the following questions.
336 ÷ 6 ÷ √16 * ? = 1400 ÷ 4
What will come in the place of question mark (?) in the given expression?
9 (? + 12) = 3 (14 + 17 - 11)
Evaluate: (768÷16)×(125÷25)−(81÷9)×12
81 ÷ 0.09 × 1.4 – 1223=?
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² = ?
