    Solution

    ATQ, The ratio between the cost price of gadget E and F is 3:2 respectively. Let’s assume the cost price of gadget E and F is 3w and 2w respectively. Each of the gadgets was marked 60% above its cost price. 3w of (100+60)% = 2w of (100+60)% + 1800 3w x 1.6 = 2w x 1.6 + 1800 1.6(3w - 2w) = 1800 w x 1.6 = 1800 w = 1125 Sum of the cost price of both of the gadgets = 3w+2w = 5w = 5x1125 = Rs.5625
