The respective ratio of salaries of A and B is 8:7, if the salary of B increases by 20% and the salary of A increases by 21% the new ratio becomes 96 : 77 respectively. What is A's salary?
Rs. 22,560/-
Rs. 21,600/-
Rs. 20,640/-
Rs. 23.040/-
Cannot be determined
Answer : Option E.
Only ratio of the salary is given, but salary is not given, so we cannot determined the salary of A . Hence answer is option E.
(1/3)rd the diagonal of a square is 2. What is the measure of the side of the concerned square?
12 m
9 m
18 m
6 m
7 m
Answer : Option B.
Let a be the side of a square.
Therefore, diagonal (d) = √2a
We are given that
Hence the answer is option B.
((441)1/2 * 207 * (343)1/3)/ ((14)2*(529)1/2)=?
61⁄2
51⁄2
53⁄4
63⁄4
61⁄4
Answer : Option D.
((441)1/2 * 207 * (343)1/3)/ ((14)2*(529)1/2)=?
=> 21 * 207 * 7/196*23 = 63/4
Hence the answer is option D.
3/8 of {4624 / (564-428)} = ?
131⁄4
141⁄4
115⁄6
123⁄4
121⁄8
Answer : Option D.
= 3/8 of {4624/ 136}
= 3/8 of 34
Hence the answer is option D.
33⁄8 * 65⁄12 - 23⁄16 * 31⁄2 = ?
21
18
14
15
16
Answer : Option C.
? = 33⁄8 * 65⁄12 - 23⁄16 * 31⁄2
= (27/8) * (77/12) - (35/16) * (7/2)
= (693/32) - (245/32) = 448/32 = 14.
Hence the answer is option C.
Answer : Option C.
Therefore, ? = 132 = 169
Hence answer is option C.
12 years ago the ratio between the ages of A and B was 3 : 4 respectively. The present age of B is 33⁄4 times of C's present age if C's present age is 16 years, then what is A's present age ? (in years)
48
42
60
54
36
Answer : Option A.
We are given that (A - 12) / (B - 12) = 3/4 ... (1)
and B = 33⁄4C = (15/4)C ... (2)
Since, C = 16 yrs, put this value in equation (2)
we get B = (15/4) * 16 = 60 years.
Now put this value in equation (1), we get
A - 12 = (3/4) * (60-12) = 36
=> A = 48 yrs.
Hence answer is option A.
M, N, O and P divided Rs. 44,352/- among themselves M took (3/8)th of the money, N took (1/6)th of the remaining amount and the rest was divided among O and P in the ratio of 3:4 respectively. How much did O get as his share?
Rs. 9,600/-
Rs. 20,600/-
Rs. 10,300/-
Rs. 8,700/-
Rs. 9,900/-
Answer : Option E.
Share of M = (3/8) * 44352 = 16632/-
Remaining amount = 44352 – 16632 = 27720/-
Share of N = (1/6) * 27720 = 4620/-
Remaining amount = 27720 – 4620 = 23100/-
Share of O = (3/7) * 23100 = 9900/-
Hence answer is option E.
3 ? 14 55 274 1643
11
5
6
8
7
Answer : Option B.
>Here the given pattern is:
3 ? 14 55 274 1643
The pattern:
3 × 2 – 1 = 5, 5 × 3 – 1 = 14
14 × 4 – 1 = 55, 55 × 5 – 1 = 274
274 × 6 – 1 = 1643, So ? = 5
Hence answer is option B.
The perimeter of a rectangle whose length is 6m more than its breadth is 84m. What would be the area of a triangle whose base is equal to the diagonal of the rectangle and whose height is equal to the length of the rectangle? (in m2)
324
372
360
364
348
Answer : Option C.
Let l, b and d be the length, breadth and diagonal of the rectangle
Therefore, l – b = 6 and 2(l + b) = 84 or l + b = 42
Solving the above equations, we get l = 24m and b = 18m
Therefore, d2 = ( l2 + b2) Putting the values, we get
d2 = 242 + 182 = 576 + 324 = 900 => d = 30m
Let b and h be the base and height of the triangle
We are given that b = d = 30m and h = l = 24m
Thus, area of triangle = (1/2)bh = (1/2) * 30 * 24 = 360 m2
