Please mark my answer as the brainliest. I have written the answer in English so if there's any inconvienence I am sorry.
Step-by-step explanation:
9. LCM OF 5 AND 4 = 20
SO LET THE NUMBER OF LEMONS BOUGHT BE 20.
CP OF 5 LEMONS= Rs 1
CP of 1 lemon = 1/ 5 = 20 paise
CP of 20 lemons = 20 * 20 = 400 paise = Rs 4
SP of 4 lemons = Rs 1
SP of 1 lemon = 1/4 = 25 paise
SP of 20 lemons = 25*20 = 500 paise = Rs 5
So CP = Rs 4 and SP= Rs 5
Since SP is bigger than CP so it is a case of gain.
Gain = 5 - 4 = Rs 1
Gain percent = 1 / 4 *100 = 25 percent
10. SP= Rs 1100
Gain percent = 10 percent
let the CP be x. So,
CP = 100/100+10 * 1100
CP = 100/110 *1100
CP = RS 1000
Loss percent on second bicycle = 20 percent
SP= 100-20/100 * 1000
SP = 80/100 * 1000
SP = RS 800
Total SP = 1100+1100 = RS 2200
Total CP = 1000+800= Rs 1800
Since SP is more than CP so it is a case of profit.
Gain = 2200 - 1800 = Rs 400
Gain percent = 400/1800 *100 = 22.22 percent
