**Answers**
** Solution: 1-10**
**1. Answer -** C

**Explanation:**
Amount after 2.5 yrs = 3525, after 2 yrs = 3420
So SI for half yr = 3525 – 3420 = 105, so for 1 yr SI = 105 × 2 = 210
P + 2 × SI = 3420
So P = 3420 – 2 × 210 = 3000
So 3000 × r × 2/100 = 420

**2. Answer -** A

**Explanation:**
Divide both equations, [1 + r/100] = 37044/35280 = 21/20
So P[21/20]2 = 35280

**3. Answer -** C

**Explanation:**
When the same quantity is sold at the same price and percent gain and loss are the same then there is always loss
occurred.
To calculate the loss per cent = [latex]{Common loss or gain}^{2}[/latex]/10
i.e.,[latex]{25/10}^{2}[/latex] = 6.25% loss

**4. Answer -** D

**Explanation:**
d/6 -40/60 = d/8 + 12/60
d/6 - d/8 = 12/60 - 40/60
2d/48 = 52/60
D= 52 × 40/60 × 2 = 20.8 = 21km

**5. Answer -** C

**Explanation:**

( [latex]{Time taken by 1st train after meeting}^{1/2}[/latex]
/ [latex]{Time taken by 2nd train after meeting}^{1/2}[/latex])

**6. Answer -** A

**Explanation:**
Rohit = x, Ronit = x+10
(x + 10) – 15 = 2 (x – 15)
Solve, x = 25
Ronit's 6 years after = x + 10 + 6

**7. Answer -** A

**Explanation:**
Let the ages of these are A, B, C, D, E
So A + B + C = 84 × 3 = 252
And A + B + C + D = 80 × 4 = 320
So D = 320 – 252 = 68, so E = 68 + 3 = 71
Now B + C + D + E = 79 × 4 = 316
(A + B + C + D) – (B + C + D + E) = 320 – 316
So A – E = 4, so A = 71+ 4

**8. Answer -** B

**Explanation:**
(A + C) = [latex]\frac{ 1 }{10}[/latex] + [latex]\frac{ 1 }{15}[/latex] = [latex]\frac{ 1 }{6}[/latex].
They worked for 4 days so did [latex]\frac{ 1 }{6}[/latex] × 4 = [latex]\frac{2 }{3}[/latex]rd of work
Remaining Work = 1 - [latex]\frac{ 2 }{3}[/latex] = [latex]\frac{ 1 }{3}[/latex]
Now A left, B and C working
(B + C) = ([latex]\frac{ 1 }{12}[/latex] + [latex]\frac{ 1 }{15}[/latex]) = [latex]\frac{ 9 }{60}[/latex] = [latex]\frac{ 3 }{20}[/latex].
They worked for x days and completed 1/3rd of work so 3/20 × x = 1/3, so x = 20/9 days
Total = 4 + [latex]\frac{ 20 }{9}[/latex]

**9. Answer -** C

**Explanation:**
([latex]\frac{4}{12}[/latex] - [latex]\frac{3}{15}[/latex]) × t = 1
t = [latex]\frac{15}{2}[/latex] minute – in this time the tank will be filled. So the capacity = [latex]\frac{15}{2}[/latex] × 10 = 75 litre

38 + [latex]{7}^{2}[/latex] + 3 = 90
90 + [latex]{9}^{2}[/latex] + 4 = 175
175 + [latex]{11}^{2}[/latex]+ 5 = 301

**15. Answer -** D

**Explanation:**
7 × 2 + 3 = 17
17 × 2 + 5 = 39
39 × 2 + 7 = 85
85 × 2 + 9 = 179
179 × 2 + 11 = 369
369 × 2 + 13 = 751

** Solution: 16-20**
**16. Answer -** A

**Explanation:**

y = 0.33, –2

**19. Answer -** B

**Explanation:**
[latex]{17}^{2}[/latex] + 144 ÷ 18 = x
x = 297
[latex]{26}^{2}[/latex] – 18 × 21 = y
y = 676 – 378 = 29

**20. Answer -** D

**Explanation:**
[latex]{30x}^{2}[/latex] + 11x + 1 = 0
[latex]{30x}^{2}[/latex] + 6x + 5x + 1 = 0
x = – 0.16, –0.19
[latex]{42y}^{2}[/latex] + 13y + 1 = 0
