Q.

x = 8!!
y = 5!!

————————————–

20x + 9x – 5y

= 20(8!!) + 9(8!!) – 5(5!!)

= 20(8×6×4×2) + 9(8×6×4×2) – 5(5×3×1)

= 20(384) + 9(8×6×4×2) – 5(5×3×1)

= 20(384) + 9(384) – 5(5×3×1)

= 20(384) + 9(384) – 5(15)

= 7.680 + 9(384) – 5(15)

= 7.680 + 3.456 – 5(15)

= 7.680 + 3.456 – 75

= 11.136 – 75

= 11.061
