100+ Percentage Questions for IBPS PO, SO, Clerk Exams Pdf - 1

Ans: C

Increased income = 114% of 13500 = Rs. $$({114}/{100} × 13500)$$ = Rs. 15390.

Increased expenditure = 107% of Rs. 9000
                                = Rs. $$({107}/{100} × 9000)$$ = Rs. 9630.

Increased saving = Rs. (15390 - 9630) = Rs. 5760.

Original savings = Rs. (13500 - 9000) = Rs. 4500.

Increase = Rs. (5760 - 4500) = Rs. 1260.

∴ Increase % in savings = $$({1260} / {4500} × 100)$$% = 28%.

Ans: B

Let, his income be Rs. 100.

Saving = Rs. 10.

Expenditure = Rs. 90

Increased income = Rs. 120

Increased expenditure = Rs. 110

Increased in expenditure = $${110 - 90} / {90} × 100$$ = $${200} / {9}$$ = $$22{2}/{9}$$%.

Ans: D

Let the number of valid votes be x.

Then, 60% of x = 255000 ⇒ x = $$({255000 × 100} / {60})$$ = 425000.

Number of invalid votes = (500000 - 425000) = 75000.

∴ Required percentage = $$({75000} /{ 500000} × 100)$$% = 15%.

Ans: A

Weight of water in 60 gms mixture

                                = 75% of 60 gm = $$({75}/{100} × 60)$$ gm = 45 gm.

Weight of water in 75 gms mixture = (45 + 15) gm = 60 gm.

∴ Required percentage = $$({60}/{75} × 100)%$$ = 80%.

Ans: B

Given expression = $${3456}/{12} ÷ 8$$ = 288 ÷ 8 = 36.
