Simplification Questions for SBI PO

Q1) What will come in the place of question mark (?) in the given expression?

60% of (15% of 2500 + 40% of 2500 + 20% of 2500) = ?² – 100

a. 25

b. 40

c. 45

d. 35

e. 55

Answer: d

Solution:

60% of (15% of 2500 + 40% of 2500 + 20% of 2500) = ?² – 100

0.60 × (0.15 × 2500 + 0.40 × 2500 + 0.20 × 2500) + 100 = ?²

0.60 × (375 + 1000 + 500) + 100 = ?²

?² = 1225

? = 35

Hence, option d.

Q2) What will come in the place of question mark (?) in the given expression?

1000÷ 250 = (³√? × √1444) ÷ (³√512 × √361)

a. 2744

b. 5412

c. 4096

d. 512

e. 3375

Answer: c

Solution:

1000÷ 250 = (³√? × √1444) ÷ (³√512 × √361)

4 = (³√? × 38) ÷ (8 × 19)

38 × ³√? = 4 × 8 × 19

³√? = 16

? = 4096

Hence, option c.

Q3) What will come in the place of question mark (?) in the given expression?

14% of 300 + 12% of 450 – 25% of √(9² – √289) = ?

a. 94

b. 98

c. 115

d. 84

e. 78

Answer: a

Solution:

14% of 300 + 12% of 450 – 25% of √(9² – √289) = ?

0.14 × 300 + 0.12 × 450 – 0.25 × √(81 – 17) = ?

42 + 54 – 2 = ?

? = 94

Hence, option a.

Q4) What will come in the place of question mark (?) in the given expression?

[(6√3 × 5√2) × (2√2 × 8√3) ÷ 16] = ?

a. 200

b. 160

c. 192

d. 165

e. 180

Answer: e

Solution:

[(6√3 × 5√2) × (2√2 × 8√3) ÷ 16] = ?

[(30√3 × √2) × (16√2 × √3) ÷ 16] = ?

30 × 3 × 2 × 16 ÷ 16 = ?

? = 180

Hence, option e.

Q5) What will come in the place of question mark (?) in the given expression?

³√3375 × 12.5% of 8040 – (16²× ?²) = 2531

a. 4

b. 16

c. 11

d. 7

e. 22

Answer: d

Solution:

³√3375 × 12.5% of 8040 – (16²× ?²) = 2531

2531 = 15 × 1005 – (256 × ?²)

(256 × ?²) = 15075

256 × ?² = 12544

?² = 49

? = 7

Hence, option d.
