Question: 3

The simplification of $$({75983 × 75983 - 45983 × 45983} / {30000})$$ yields the result

(A) 121796

(B) 121866

(C) 121956

(D) 121966

Ans: D

Given expression = $${(75983)^2 - (45983)^2} / {75983 - 45983}$$

                           = $${(75983 - 45983)(75983 + 45983)} / {(75983 - 45983)}$$

                           = 75983 + 45983 = 121966.

Question: 4

Find the value of $$(1 - {1}/{3}) (1 - {1}/{4}) (1 - {1}/{5}) ….. (1 - {1}/{100})$$

(A) $${1}/{20}$$.

(B) $${1}/{30}$$.

(C) $${1}/{50}$$.

(D) $${1}/{70}$$.

Ans: C

Given expression = $${2}/{3} × {3}/{4} × {4}/{5} × …. × {99}/{100}$$ = $${2}/{100}$$ = $${1}/{50}$$.

Question: 5

$$(- 5) (4)(2)({-1}/{2}) ({3}/{4})$$ = ?

(A) 10

(B) 15

(C) -15

(D) 30

Ans: B

Given expression = $$(5 × 4 × 2 × {1}/{2} × {3}/{4})$$ = 15.
