Solution:

Cost of a mouse = 4000.

Cost of a keyboard = 4000 × 6 = 24000

Cost of a table = 4000 × 12.5 = 50,000

Cost of a CPU = 50,000 + 2000 = 52,000

Cost of Chair =

\frac{2}{5}

× 50,000 = 20,000

Cost of monitor = 20,000 ×

\frac{130}{100}

= 26,000

Cost of mouse 20% increament = 4000 ×

\frac{120}{100}

= 4,800

Cost of Keyboard increment = 24,000 ×

\frac{130}{100}

= 31,200

Cost of Desktop = monitor + CPU + Keyboard + mouse

Cost of Desktop = 26,000 + 52000 + 31,200 + 4800 = 114,000
