Solutions:
ย
1.ย Reqd amount = (44/0.88) = 50 quintals.
ย
2.ย Let the speed of the slower motorcyclist be x km/hr. Therefore the speed of the faster motorcyclist will be (x + 5 ) km/hr.
In 2 hrs both motorcyclists cover
2x + 2(x+5) = (4x + 10) km distance.
i.e 4x + 10 = 220 – 30
or, 4x= 180 or, x=45
Ratio = 50 : 45 = 10 : 9
ย
3.ย Let original area plouged daily = x hectares
Total area plouged = 16x
If(x + 18) hectares is plouged daily, then total area = 10(x+18)
Given that, 16x= 10(x + 18)
Or, x=30 hectares
โด Total area of field = 16 ร 30 = 480 hectares
ย
4.ย Net profit on the article
= + 20 โ 15- (20ร15/100) = +2%
Selling price of the article = 425 ร 1.02
= Rs. 433.50
ย
5.ย By method of Alligation:
ย
Ratio = 70/12 = 35.6
For each part of liquid I, 6/35 part of liquid II should be added. So for 700 ml of liquid I, 120ml of liquid II should be added.
ย
PQ= length of the building
Given RM = 12 m, PM = 8m and
In โPQR
Tan 60ยฐ = [(8 + MQ) / RQ] or, RQ= [(8+MQ) / โ3]
In โMQR
(RM)ยฒ = (MQ)ยฒ + (RQ)ยฒ
Or, (12)ยฒ = (MQ)ยฒ + [(8+MQ) / โ3]2
or, MQ โ 8m
Height of the building = PM + MQ = 8 + 8=16m
ย
7.ย [(xยณ + 3x) / (3xยฒ + 1)] = (1241/217)
Using componendo and dividend, we get
[(xยณ + 3x + 3xยฒ + 1) / (xยณ + 3x โ 3xยฒ – 1)] = [(1241+217) / (1241-217)]
or, (x+1)ยณ / (x-1)ยณ = 1458 / 1024
or, [(x+1) / (x-1)]ยณ =ย  (9/8)ยณ
or, (x+1 / x-1) = (9/8)
or, 8x + 8 = 9x โ 9 or, x=17
ย
8.ย Reqd no. of bottles = (2/3ฯ (27)ยณ / ฯ(3)ยฒ6) = 243
ย
9.ย In a three-digit no. with 7 at unitโs place, zero canโt be there at hundredโs place. So, hundredโs place can be filled with any of the digits from 1 to 9. Thus there are 9 options.
Tenโs place = digits 0 to 9 = 10 options
Unitโs place = 7 = 1 option
โด no. of required numbers = 9 ร 10 ร 1 =90
