Question

_% × 260 + 50% × 440 = 324. Find the missing number.

Answer 1

Answer:

40

Step-by-step explanation:

let, missing number be 'x'

x℅ × 260 + 50℅ × 440 = 324

x/100 × 260 + 50/100 × 440 = 324

x/10 × 26 + 5 × 44 = 324

x/10 × 26 + 220 = 324

x/10 × 26 = 324 - 220

x/10 × 26 = 104

x/10 = 104/26

x = 4 × 10

x = 40℅
