B) The cost price of an electronic fan is Rs 2,800. If the shopkeeper marks its price
30% above the cost price and sells it at 10 % discount, how much should a
customer pay for it with 15 % VAT?

cp=2800

mp=cp+30%of cp=2800+30/100×2800=3640

discount=10%

discount amount=10%ofmp=10/100×3640=364

sp=mp-discount=3640-364=3276

vat=15%

sp with vat=sp+vat%of sp=3276+15/100×3276=3276+491.4=3767.40

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
