Reg­u­lar prac­tice can help can­di­dates improve cal­cu­la­tion speed, rea­son­ing abil­i­ty, accu­ra­cy and time man­age­ment before the examination.

The ques­tions in this prac­tice set are orig­i­nal prepa­ra­tion ques­tions based on the rel­e­vant SSC CPO exam­i­na­tion style and are intend­ed for prac­tice rather than rep­re­sent­ing an offi­cial SSC ques­tion paper. SSC con­ducts the exam­i­na­tion through its offi­cial recruit­ment sys­tem and pub­lish­es exam­i­na­tion notices and instruc­tions on its website

Scurvy is caused by a defi­cien­cy of Vit­a­min C (ascor­bic acid).

Prof­it = 920 — 800 = ₹120. Prof­it% = (120/800) × 100 = 15%.

13. The average of 18, 24, 30, 36 and 42 is:

The sen­tence is in sim­ple past tense. Its pas­sive form is “The thief was arrest­ed by the police.”
