The correct Answer is:
C


विकल्प(1)
` 18 - 6 xx 7 div 2 + 8 = 63`
` rArr 18 div 6 + 7 - 2 xx 8 = 63`
` rArr 3 + 7 - 16 ne 63`
विकल्प (2)
` 18 div 6 + 4 - 2 div 3 = 22 `
` rArr 18 - 6 xx 4 div 2 - 3 = 22`
` rArr 18 - 6 xx 2 - 3 = 22 `
` rArr 18 - 12 - 3 ne 22`
विकल्प (3)
` 18 + 6 - 4 xx 2 div 3 = 26`
` rArr 18 xx 6 div 4 + 2 - 3 = 26`
` rArr 27 + 2 - 3 = 26`
विकल्प(4)
` 18 xx 6 - 4 + 7 xx 8 = 47`
` rArr 18 + 6 div 4 xx 7 + 8 = 47`
` rArr 18 + 3/2 xx 7 + 8 = 47`
` rArr 18 + (21)/2 + 8 = 47`
` rArr (36 + 21 + 16)/2 = 47`
` rArrr 73 ne 47 xx 2`
