Question

Vinod sold a watch to Alex at a gain of 12% and Alex has to sell it to Heena at a loss of 5%.
If Heena paid * 1330 for it, how much did Vinod pay for the watch?​

Answer 1

Answer:

vinod paid 1250 for the watch

Step-by-step explanation:

heena paid 1330 for watch by 5% discount means,

X - X * 5/100 = 1330

X - 5X/100 = 1330

(100X - 5X) / 100 = 1330

95X / 100. = 1330

95X = 1330 *100

X = 133000 ÷ 95

X = 1400

SO, Alex paid 1400 to vinod for the watch, then

X + (X * 12) ÷ 100 = 1400

(100X + 12X) ÷ 100 = 1400

112X ÷ 100. = 1400

112X = 1400 * 100

X = 140000 ÷ 112

X = 1250

so that vinod paid a amount of 1250 for the watch
