Aring is now reduced to £840 this is a saving of 40% of the original price whats the original price of the ring

1400 dollars

Step-by-step explanation:

Let the original price = 100

Less: saving of 40%   =  40

Reduced price            = 60

Reduce price of 60 is equivalent to 840 dollars

Hence original price of 100 is equivalent to

100/60 = x/840

Or x = 1400 dollars.

Original price actual = 1400 dollars.

Verify: Original price = 1400

           Less: 40%      =    560

            Reduced price  = 1400-560 =840 (given)

Hence verified

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
