what is this '=X'

Question:

DIRECTIONS: What should approximately come in place of the question mark (?) in the following question??

\(\sqrt[]{4901} \times 35.93 + x = \sqrt[]{6401} \times 490 + 3246\)

Options:
A)

25200

B)

41920

C)

38000

D)

49925

E)

39926

Solution:

Ans: (e)

\(\sqrt[]{4901} \times 35.93 + x = \sqrt[]{6401} \times 490 + 3246\)

70 x 36 +?= 80 x 490 + 3246 

2520 + ?= 39200 + 3246

? = 42446 - 2520

? = 39926

√(4901) ×35.93 +? = √(6403)×490.08+3246


?=39926
