Question : 96 [SBI-PO-2019]
4 years hence the sum of ages of A and B will be 16 years more than the sum of the present ages of B and C. 4 years ago the sum of A’s age and C’s age was 32 years, then what is the present age of C?
a) 18 years
b) 14 years
c) 10 years
d) 16 years
e) 12 years
Answer »Answer: (d)
According to the question:
Present age of A and C:
A + C = 40 ............(i)
After 4 years, sum of ages of A and B will be 16 years more than the sum of the present ages of B and C.
A + 4 + B + 4 = B + C + 16
A - C = 8 ............(ii)
On solving eq(i) and eq(ii).
2A = 48
A = 24
Then, the present age of C:
24 + C = 40
C = 16 Years
Question : 97 [SBI-PO-2019]
40 men can complete a work in 48 days. If 64 men started working and after X days, 32 more men joined the work. If the remaining work is completed in 16$2/3$ days, then find the value of X.
a) 2
b) 5
c) 8
d) 4
e) 6
Answer »Answer: (b)
By MDW formula,
Total work = 48× 40 = 1920 units
Now,
1920 = 64 × X + (64 + 32) × (50/3)
⇒ 1920 = 64X + 1600
⇒ 64X = 320
⇒ X = 5
Question : 98 [SBI-PO-2019]
Cost of gardening the circular field C at Rs.10 per meter square is Rs.3465. Side of the square field S is equals to the diameter of the circular field C. find the perimeter of square field.
a) 108
b) 84 m
c) 78 m
d) 112 m
e) None of these
Answer »Answer: (b)
Let r meter be the radius of circular field C, then
Area of circular field C × 10 = 3465
⇒ πr 2 × 10 = 3465
⇒ r 2 = $441/4$
⇒ r = $21/2$ m
Side of square field S = 2 × r = 21m
Perimeter of square field = 4 × 21 = 84 meters
Question : 99 [SBI-PO-2019]
4 years ago, the ratio of ages of A and B was 9 : 11 and 6 years hence, the ratio of ages of A and B will be 7 : 8. Find the present age of B.
a) 22 years
b) 24 years
c) 26 years
d) 37 years
e) None of these
Answer »Answer: (c)
Let the ages of A and B be 9X and 11X, then
According to the question:
$\text"9X + 10" / \text"11X + 10"$ =$7/8$
⇒ 72X + 80 = 77X + 70
⇒ X = 2
Hence, the present age of B = 11X + 4 = 22 + 4 = 26 years
Question : 100 [SBI-PO-2019]
The cost price of the two chairs is same. Difference between their selling prices is Rs. 90. On selling one chair, a person got a profit of 12% and on selling another he got a profit of 18%. Find the cost price of each chair.

So SP of first Article at 12% gain= 112x Rs.
And SP of second Article at 18% gain = 118x Rs.
ATQ,
118x – 112x= 90
6x = 90
X= 15
So CP of the Article = 100x =1500 Rs
