அடுத்தடுத்த தள்ளுபடிகள் 5%, 10% மற்றும் p%
ஒரே ஒரு தள்ளுபடி = 31.6%
கருத்து: a%, b% மற்றும் c% என்ற மூன்று அடுத்தடுத்த தள்ளுபடிகள் MP யில் இருந்தால்
SP = MP(100 - a)/100 x (100 - b)/100 x (100 - c)/100
பயன்படுத்தப்பட்ட சூத்திரம்:
SP = MP x (100 - D%)/100
D% = (D/MP) x 100
கணக்கீடு:
MP x என்று கொள்வோம்
SP = x x (100 - 5)/100 x (100 - 10)/100 x (100 - p)/100
⇒ SP = x x 95/100 x 90/100 x (100 - p)/100
⇒ x x 95/100 x 90/100 x (100 - p)/100 = x x (100 - 31.6)/100
⇒ x x 19/20 x 9/10 x (100 - p)/100 = x x 68.4/100
⇒ (100 - p)/100 = 2 x 68.4/171
⇒ (100 - p)/100 = 0.8
⇒ (100 - p) = 80
⇒ p = 20
P இன் மதிப்பு 20%.
