A. 4890
B. 40000
C. 271
D. 5996
Explanation:
105.126 * 35.201 – 90.23 * 3 + 55.11 * 27.01
= 105 * 35 – 90 * 3 +55 * 27 = 3675 – 270 + 1485
= 5160 – 270 = 4890
A. 0.1
B. 0.2
C. 0.3
D. 0.4
Explanation:
As numerator is of the form a2 – b2 = (a + b) (a – b), so the given expression simplifying becomes
(0.92 – 0.82)/(0.9 + 0.8) (0.9 + 0.8) (0.9 – 0.8)/0.9 + 0.8 = 0.1
A. 0.1
B. 0.2
C. 0.3
D. 0.4
Explanation:
As numerator is of the form a2 – b2 = (a + b) (a – b), so the given expression simplifying becomes
(0.92 – 0.82)/(0.9 + 0.8) (0.9 + 0.8) (0.9 – 0.8)/0.9 + 0.8 = 0.1
A. 1/5
B. 4/5
C. 6/5
D. 8/5
Explanation:
(5/8 * 12/5 – 5/4)/(5/4) (3/2 -5/4)/(5/4) = 1/5
A. 182/3
B. 1831/54
C. 18
D. 201/2
Explanation:
12 + 16 – 10 = 18
and 13/18 + 11/27 – 5/9 = (39 + 22 – 30)/(9 * 2 * 3) = 31/54 The answer is 18 (31/54)
A. 3
B. 2
C. 4
D. 6
Explanation:
(5 * 5)/5 + 1/5 * 5 = 5 + 1 = 6
A. 12
B. 18
C. 20
D. 30
Explanation:
36 * 48 / 64 + 36/12 = 27 + 3 = 30
A. 4
B. 0.1
C. 1
D. 0.4
Explanation:
? % of 400 + 40% of 160 = 17% of 400
?/100 of 400 + 40/100 of 160 = 17/100 of 400
?(4) + 64 = 68 => ? = 1
A. 2080
B. 2480
C. 2260
D. 2380
Explanation:
Since, 40.1 = 40
52 * 40 = 2080
A. 44000
B. 24500
C. 34500
D. 26000
Explanation:
22004 – 29303 + 101299 – 59532
123303 – 888.35 = 34468 = 34500
