= (69x85/3x100) + 10.7
= 30.25.
534.596 + 61.472 ? 496.708 = ? + 27.271
596.068 ? 496.708 = ? + 27.271
? = 99.36 ? 27.271
? = 72.089.
504/42 × 7 - 63 + 28 = 84 ? 63 + 28 = 49
Hence option 5 is correct.
(150 x 460)/100 + (24 x 650)/100
= 690+156
= 846
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
