Kishore owns a factory of plastic goods. His production cost comprises only the cost of raw material and labour . The cost of raw material increases by 20% and the labour cost also increases from 20% to 25% of the cost of raw material. By how much percent should he reduce his consumption of raw material and labour so that his production cost remains unchanged?1)20%2)15%3)17%4)25%5)None of these
let initial consumption of raw materials be - x

total initial consumption= x+0.2x=1.2x

final consumption = 1.2x+0.3x=1.5x

1.2/1.5*100 = 80%

so 20% reduction

@ScareCrow28 ne thik kiya he generalized it.Calculate kar k dekho 35/6 hi a rha.PS: I think he has edited it and has come to @grkkrg and my side with final ans 35/6
yes u right...@ScareCrow28 .."scare"crow....

Somehow ScareCrow has become a ScaredCrow from many days.. Sorry for spamming and "those silly mistakes"

Nahi dekh simple hai hexagon ke har vertex se perpendicular draw karo 2 wahan tk coin ka centre straight travel karega till its just above the vertex (perpendicularly)Uske baad curved path me tb tk jab tk its just above other side (agn perpendicular)So straight distance in essence equals to the length of sideNow angle k liye360-(90+90+60)=120
lekin isse angle 360-(90+90+120)=60 ayega...120 nai..

Bro
Firstly..how u have concluded that Labour cost will be 0.2X??
Secondly, I think 1.2x-1.5x/1.5x*100=20% Hoga??? He should be reduce his consumption.

Shouldn't the angle be 360-(90+90+120)=60 ?

1) 20%


R' = 1.2R
L = 0.2R
L' = 0.25R' = 0.3R

New cost = 1.2R + 0.3R = 1.5R
Old cost = R + 0.2R = 1.2R

(1.5R)C' = (1.2R)C
C' = 0.8C

yaar maine kab ka edit kar dia, still u caught me

its given that labor cost was 20% of the cost fo raw materials

Bro Labour cost is considered 20% of raw material cost... As per question language...

"and the labour cost also increases from 20% to 25% of the cost of raw material"

20%
Yup 20%
Calculation Mistake

bhai since mujhe numbers bht pasand hai to hm ise x k terms me na khelke numbers k terms me khelte hai..

suppose raw material(R) cost 100 hai..to labor cost(L) 20 hui.
to total production cost(p) 120 hui..
now R cost 20% badi..so R is now 120...and L 20 se 25% badi..to 25% of 120= 30 hui
therefore total cost 150 hui.

now back to pavilion situation me 150 se 120 ana hai..means 30 reduce karna..which is 30/150==20%
