Question

If the cost of mobile phone is three quarters the cost of washing machine and microwave is quarter the cost of washing machine , what is the cost of mobile phone?

Total cost of all the items = ₹ 46,000

• A. ₹ 5,000
• B. ₹ 5,750
• C. ₹ 23,000
• D. ₹ 17,250

Answer 1

The correct option is D ₹ 17,250

Total cost = ₹ 46,000
Total cost
= Cost of mobile phone + Cost of washing machine + Cost of microwave


Also,
Cost of mobile phone = three - quarter the Cost of washing machine
Cost of microwave = Quarter the Cost of washing machine

Cost of mobile phone and microwave together
= Quarter the Cost of washing machine + three- quarter the cost of washing machine

= Cost of washing machine

Quarter + three - quarters = 1

Therefore,
Total cost
= 2 $\times$ Cost of washing machine

Cost of washing machine
= ₹ 46,000 $÷$ 2
= ₹ 23,000

Cost of mobile phone = three -quarters of ₹ 23,000

= $\frac{3}{4}$ $\times$ ₹ 23,000

= ₹ 17,250
