Ans.
?(3100 ÷ 62 + 14) = ?
?(50 + 14) = ?
?64 = ?
? = 8
Ans.
112 × 5 ÷ 14 = 11 + ?
112 × 5 ÷ 14 = 11 + ?
560 ÷ 14 = 11 + ?
40 = 11 + ?
? = 40 - 11 = 29
Ans.
25% of 84 ÷ 7 = ?
[(25 × 84)/100]÷ 7 = ?
21÷ 7 = ?
? = 3
By replacing the ??? with ?x?
(12.5×14÷8.75) x (100/100) + 42 = 50 + X
(125*140)/875 + 42 = 50 + X
140/7 + 42 = 50 + X
20 + 42 = 50 + X
62 = 50 + X
X = 62 - 50
X = 12
(150 x 460)/100 + (24 x 650)/100
= 690+156
= 846
Ans.
(184 - 6) × 30 = ?
178 × 30 = ?
? = 5340
Ans.
53 - 345 ÷ 23 = 2 ×(?)
53 - 15 = 2 ×(?)
38 = 2 ×(?)
? = 19
Ans.
Approximating the values:
(?81 - ?25) × (?121 + ?16) = ?
(9 - 5) × (11 + 4) = ?
4 × 15 = ?
? = 60
