Question 11 of 20
11. Question
Kalyan can do a work in 18 days. He works alone for 4 days and Naveen alone finishes the remaining work in 21 days. Both of them together can complete the work in?
Correct
Answer: d)
Kalyan’s one day work = 1/18
4 days work = 4/18 = 2/9
Remaining work = 1 – (2/9) = 7/9
Naveen alone finishes the remaining work in 21 days.
= > (7/9)*Naveen’s whole work = 21
= > Naveen’s whole work = 27 days
Kalyan and Naveen’s one day work,
= > (1/18) + (1/27)
= > 5/54
Both Kalyan and Naveen together complete the work in,
= > 54/5 days = 10 4/5 days
Incorrect
Answer: d)
Kalyan’s one day work = 1/18
4 days work = 4/18 = 2/9
Remaining work = 1 – (2/9) = 7/9
Naveen alone finishes the remaining work in 21 days.
= > (7/9)*Naveen’s whole work = 21
= > Naveen’s whole work = 27 days
Kalyan and Naveen’s one day work,
= > (1/18) + (1/27)
= > 5/54
Both Kalyan and Naveen together complete the work in,
= > 54/5 days = 10 4/5 days

Question 15 of 20
15. Question
Rajiv, Kalai and Mano started a business by investing Rs. 180000. Rajiv invests Rs. 40000 more than Kalai and Mano invests Rs. 20000 more than Kalai. If the total profit at the end of the year is Rs. 81000, then find the share of Rajiv?
Correct
Answer: a)
Let Kalai’s investment be x,
Rajiv’s investment = x + 40000
Mano’s investment = x + 20000
According to the question,
X + x + 40000 + x + 20000 = 180000
3x = 180000 – 60000
3x = 120000
X = 40000
The share of Rajiv, Kalai and Mano
= > 80000: 40000: 60000
= > 4: 2: 3
The share of Rajiv = (81000/9)*4 = Rs. 36000
Incorrect
Answer: a)
Let Kalai’s investment be x,
Rajiv’s investment = x + 40000
Mano’s investment = x + 20000
According to the question,
X + x + 40000 + x + 20000 = 180000
3x = 180000 – 60000
3x = 120000
X = 40000
The share of Rajiv, Kalai and Mano
= > 80000: 40000: 60000
= > 4: 2: 3
The share of Rajiv = (81000/9)*4 = Rs. 36000

Direction (1-5) :
1). Answer: c)
(2/5)*(3/7)*16975 – x + (37/100)*1250 = 58
2910 – x + 462.5 = 58
2910 + 462.5 – 58 = x
X = 3314.5
2). Answer: a)
(5/9)*5166 + (64/100)*1750 = x^{2} + 146
2870 + 1120 – 146 = x^{2}
3844 = x^{2}
X = 62
3). Answer: b)
x – 17^{2} ÷ 459 ×702 + 13^{3} = 46 % of 7200 + (56793 ÷ 11)
