Let P receives Rs x P = 3/7(Q+R ) ⇒ x = 3/7(Q+R ) ⇒ 7/3 x = Q + R & we know that P+Q+R = 2100 So x + 7/3 x = 2,100⇒ 10/3 x = 2,100 ∴x = Rs 630 Now, 7/3 x = Q + R ⇒ 7/3 ×630= Rs 1,470 ∴ Q + R = Rs 1,470………………. .(i) Q = 2/3 (P+R )⇒ Q = 2/3 (630+R) ⇒ 3 Q = 1,260 + 2 R ∴ 3Q – 2R = Rs 1,260…………………… (ii) Solving (i) and (ii) , we get Q’ share = Rs 840 ALTERNATE SHORTCUT METHOD: Q = 2/3 (P+R ) OR P+R = 3/2Q ---(i) & we know that P+Q+R = 2100 ---(ii) So putting equation (i) in (ii), Q+ 3/2Q = 2100 Or 5/2Q = 2100 or Q = 2100/5×2=840
? = 340.24 + 1001.97 – 6.992
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
? * 9.34 = (275.09 ÷ 8.89) % of 5125 - 1150.88
20.22% of (74.9 × 6.01) + 69.97 =?
