Let the Marked Price be Rs x. Here, Discount%(D%) = 15% So, Selling Price(SP) = MP - D% of MP  or, 4250 = x - 15x/100 or, 85x/100 = 4250 Therefore, x = Rs. 5000. Therefore, MP = Rs. 5000. Now, given that, MP is 25% of CP. So, CP + 25% .....

You must get marked price, x = Rs. 2500. Subtitute the value of x in any of the equation,  cost price = 125 + 0.75x cost price = 0.9x - 250 you will get the cost price of the .....

Let the Marked Price(MP)  be x. 1st condition: D% = 10%. Therefore, SP  = MP - D% of MP = x - 10% of x = 9x/10. Here, Loss amount = Rs. 60. Therefore, CP = SP + Loss amount = Rs. (9x/10 + 60) Again, 2nd condition: D% = .....

Let the Marked Price (MP) = Rs x. 1st condition: Discount%(D%) = 10%. Gain% = 20%. Therefore, SP = x - 10% of x = x - x/10 = 9x/10. Therefore, SP1 = Rs. (9x/10). Using CP = SP*100/( 100 + P%) = (9x/10)* 100/( 100 + 20)  = .....

Let the Marked price(MP) be Rs. x. Here, Discount% (D%) = 20%   or, SP= MP - D% of MP  = x - 20x/100 = 4x/5. Now, when 10% VAT is added, SP with VAT = SP + VAT% of SP = 4x/5 + 10/100 * 4x/5 = 4x/5 + 4x/50 = 2376 or, 22x/25 = .....

Here MP = Rs.5000 Discount % = 10% So SP = MP - discount % of MP             = 5000 - 10 / 100 x 5000 = ...............find it. VAT % =  15 %  So price after VAT = SP + VAT % of SP    .....

You know, acceleration due to gravity depends on the radius of the earth.  It is inversely proportional to the square of the radius (i.e. g ∝ 1/R2). More the radius (R), less will be the value of acceleration due to gravity .....

So, the radius of the earth is more at the equator and less at the poles. You know that, acceleration due to gravity is inversely proportional to the square of the radius of the earht, i.e., g ∝ 1/R2.  Thus, the value of acceleration .....
