जय गेव्हच्या तिप्पट वयाचा आहे. अमनचे वय गेव्हच्या वयाच्या दुप्पट आहे. जय आणि अमनच्या दोघांची वये एकत्र केली की शम्मीच्या वयाची निमपट मिळते. जर शम्मीचे वय 70 असेल, तर गेव्हपेक्षा मोठ्या असलेल्या ज्ञानचे, जो गेव्हपेक्षा दोन वर्षांनी मोठा आहे त्याचे वय किती ? Jay is three times older than Gave. Aman’s age is twice that of Gave. Addition of Jaya’s and Aman’s age is half of Shammi’s age. If Shammi’s age is 70, then what is the age of Dyan who is two years older to Gave ?
a)5
b)7
c)9✓ Correct
d)11
Shammi = 70. Jay + Aman = 70/2 = 35. Let Gave = x. Jay = 3x, Aman = 2x. So 3x + 2x = 35 => 5x = 35 => x = 7. Gave = 7. Dyan = Gave + 2 = 9.
