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.
