If 750 is 30% of y, what is 70% of y?

A)525 B)1500 C)1575 D)1750 E)2500

D. 1750

Step-by-step explanation:

750 = 30% then 1% = 750/30 which is 25

70% you multiply what 1% is by 70, which is 25x70 = 1750

Step 1:

30/100 x Y = 750

Y = 750 x 100/30

Y = 2500

Step 2

X = 70%Y

X = 70/100 x 2500

X = 1750

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.
