Options- A. Rs. 1600
- B. Rs. 1700
- C. Rs. 1800
- D. Rs. 1900
- Correct Answer
- Rs. 1600
ExplanationLet the salaries of Maneela and Shanthi one year before be M1, S1 & now be M2, S2 respectively.
Then, from the given data,
M1/S1 = 3/4 .....(1)
M1/M2 = 4/5 .....(2)
S1/S2 = 2/3 .....(3)
and M2 + S2 = 4160 .....(4)
Solving all these eqtns, we get M2 = Rs. 1600.

Correct Answer: Rs 16
Explanation:
3 pairs of gloves = 2 x 54 = 108 ; 1 pairs of gloves = 36
3 pairs of leg pads = 2 x 36 = 1 pairs of leg pads = 24
3 cricket balls = 2 x 24 = 48
cost of 1 cricket ball = 16;
Correct Answer: 12
Explanation:
Simple Interest = S.I= pnr/100 Given, S.I = 23940 , p = 28500 , n = 7 thus, r = 100x23940/28500x7 = 12
Correct Answer: 52
Correct Answer: None of the above
Explanation:
The CP of profitable cow = 9900/1.1 = 9000
and profit = Rs. 900
The CP of loss yielding cow = 9900/0.8 = 12375
and loss = Rs. 2475
so, the net loss = 2475 - 900 = 1575
Correct Answer: 4
Correct Answer: 5/?3
Correct Answer: 35%
Explanation:
Given the cost price of the articles = Rs. 450
To get overall 20% gain,
Total Selling Price = (20/100) x 450 = 540
One third of the CP = 1/3 x 450 = Rs. 150
But given 1/3 of articles are sold at 10% loss
S.P of 1/3 of articles = 90% of 150
= 90 x 150/100 = 135
Then, S.P on remaining 2/3 goods must be
= 450 - 135 = 405 ...........(1)
CP on remaining goods
= 2/3 x 450 = 300 ............(2)
Profit = SP - CP = 405 - 300 = 105
Profit % = (105/300) x 100
= 35%.
Correct Answer: 70%
Explanation:
Let C.P.= Rs. 100.
Then, Profit = Rs. 320,
S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295
Required percentage = (295/420) * 100
= 70%(approx)
Correct Answer: 6
